the weird projection geometry

the color gamut can cover nearly 90% of the human eye can recognize colors, to the most perfect natural colors. May 19, 2009, the twelfth Tech Expo International Exhibition Center in Beijing was held in Beijing Optoelectronic Technology Co., Ltd., as the subjects exhibited self-developed 65 in laser TV. The color space, color saturation, respectively, is the traditional standard television display and 2 times 100 times. The school plans to buy more laser pointer .
The new image reproduction technology leverages the advantages of the laser itself. In the mode of transmission of light, laser light source with the traditional incandescent lamp has a fundamentally different: ordinary incandescent light emission in all directions, and laser light are all gathered in a parallel beam. In addition, the laser projector projector can express more than the traditional range of colors, providing clearer images. High-resolution laser projector can be used to make traditional projector does not apply in some areas. The current widely used traditional projector lamps with halide can not be free to the projection room four, because the lens can only show very small distortion compensation, so in principle should show projector near the axis, generally located in the middle of the room. Whether vertical or horizontal angle laser light to the screen, the effect is the same, there is no distortion. Even the weird projection geometry, such as an arched screen, or even a round screen, laser projection does not produce anywhere ambiguous phenomenon. This characteristic of the laser projector to create a show for the ring - a bright future. In practice, there are many other advantages of laser technology: compact projection head can be separated from the laser unit; laser unit can be hidden in the room, only a small projection head sticking out; generated by the tilt distortion can be shown very simple correction and so on. More laser pointer  will be purchased for the party.
Laser display as a new generation of display technology with superior low power consumption characteristics. If you want to show 60 in the image, the white light laser synthesis usually takes 20 w power is sufficient, if the luminous efficiency of 10% according to calculations, the whole power consumption of only 200 w.

the vertical axis is energy use

Such a light beam in the way of lighting and control design of our optical system has been lighting the way some revolutionary changes. At the same time, an excellent degree of polarization of laser light source, a km on the degree of polarization, such that the degree of polarization and polarization for LCD display technology, it can be significant savings in raw materials, and its contrast than the current degree of polarization to much higher. Light bulbs and LED light source with a completely different, because the optical properties of laser light, in a small chip can achieve a high light utilization efficiency. The wavelength of  laser pointer  should be in details. The wavelength of laser pointer can be various. The teacher has bought more laser pointer . This graph abscissa is the chip size, the vertical axis is energy use. Lighting light bulbs to use with the chip size decreases, its energy utilization efficiency is relatively low. For the laser, the basically unchanged, because the direction of the laser is good. Compared the number of applications, such as micro-display rear projection or projector or movie projector, even if such a monster for the movie projector, if as a million people if the display, then the required laser light power is nothing but 140 W, if the development of the laser device is good enough, it needs to consume only 25 watts of electrical power, so low power consumption and high efficiency, in fact, expanded the number of high-energy, large-screen display or in a variety of applications applications of the application. The student needs more laser pointer .
Display industry is a modern high-tech industry, an important component of modern information society is an important foundation for the development of industry. After a black and white display technology display, color display to the digital display, the program has completed the transition to high-resolution, digital changes. However, the current color space display products covered by the human eye can only identify the color space of 31.8%, difficult to truly restore the natural color, it has become important to further improve the display quality of the barrier. As a new generation of display laser display technology, inherited all the advantages of digital display technology, based on the high saturation of red, green and blue color laser light source as a display, a display technology to solve the long-term difficult to solve large-gamut color reproduce the problem.

All transfers are started by the host, the firmware designed to completely interrupt-driven, when the CPU processing the foreground task, USB transfer can be in the background. This ensures the best transmission rate and better software structure. USB host system firmware write more complicated, mainly related to the USB control transfer, USB bulk transfer, mass storage class protocol, UFI disk operating commands and write FAT file system, all the bottom of the program operation, there is no ready-made library support. The effective tool of laser pointer is convenient in use and outstanding in quality.
Therefore, the overall framework of the program and specific agreements to build the organizational structure of data is critical. The main difficulty lies in the modular design of software programs written in the agreement because it involves more than, in the preparation process should pay attention to the modular idea, as each specific agreements are written in a source file, the data structures and constants, variables, most well defined in the header file for each module. USB low-level debugging of control transfer, Bus Hound can take full advantage of USB removable storage tools just crawl into your computer to communicate with the computer data analysis, comparison and reference developed to enhance information exchange on the USB understanding of the underlying. Any USB device connected to the USB host, USB-host must be configured to the correct use of enumeration. USB bus enumeration procedures and methods, for all USB devices are the same, and must comply with the standard USB protocol process, by controlling the transmission of "a question and answer" to achieve the necessary master and slave data exchange a few. The useful tool of laser pointer is fabulous in appearance.

For large gear tooth surface

And induction hardening, flame hardening, carburizing and quenching processes, laser hardening hardened layer, high hardness (typically higher than the induction hardening 1-3HRC), workpiece deformation is small, the heating depth and easy to control the heating path, easy to automate , did not like the induction hardening of parts of different sizes according to design appropriate induction coil. Gifts of  laser pointer  are good choices.
The processing of large parts need not be case hardening heat treatment furnace size and other chemical constraints, in many industries to gradually replace the CKS and the chemical induction hardening heat treatment and other traditional crafts. Of particular importance is the deformation of the workpiece before and after laser hardening is almost negligible, it is particularly suitable for high-precision surface treatment of parts required. The depth of the laser hardened layer in accordance with part composition, size and shape of the laser process parameters and different, usually in the range 0.3 ~ 2.0mm. For large gear tooth surface, large parts of the journal shaft quenching, the surface roughness is essentially the same, no subsequent machining to meet the needs of the actual working conditions. More gifts of  laser pointer  will be recommended to the customer.
Laser melting quenching technique is the use of a laser beam to the substrate surface is heated to above the melting temperature, the thermal conductivity of the substrate within the surface layer quickly cooled leaving the melting and solidification cooling crystallization process. Quenching obtained by melting a very dense, along the depth direction of the organization were melting - solidification layer, phase transformation hardening layer, heat affected zone and substrate. Laser melting layer than the depth of laser hardening hardening layer deeper, higher hardness, wear resistance and better. Inadequacies of the technology lies in the surface roughness of a certain degree of damage, generally require subsequent machining to recover. In order to reduce the laser melting treatment part surface roughness and reduce the amount of follow-up process, Huazhong University of Science and Technology prepared a special laser melting hardening coatings, can significantly reduce the melting layer of the surface roughness. The company has more options of  laser pointer  for the customer.

Lasers currently used mostly YAG laser, CO2 laser-based. The customer has no questions about the smooth working of  laser pointer . The RF  laser pointer  is more widely used in the market. Laser radar is a rapidly growing high-tech, in the military sector has a wide range of uses, has been of great concern to national military authorities. The international Missile Technology Control Act clearly states: "the laser system for laser radar echo ranging, direction, and by location, radial speed and the reflective properties of objects, identify the target, reflecting the special launch, scanning, receiving and signal processing techniques ", and to limit the spread of the laser radar as military technologies. Laser radar is a traditional radar technology and modern laser technology product of the combination. The second year after the advent of the laser, that in 1961, scientists proposed the idea of laser radar, and carried out research work. 40 years, the laser radar technology from the most simple laser rangefinder technology, and gradually developed a laser tracking, laser guns, laser scanning imaging, laser Doppler imaging technology, have developed a different use of laser radar, the laser radar become a class of systems with multiple functions. The RF  laser pointer  can get more customers.
The reason why laser radar attention, because it has a unique set of advantages: a high angular resolution, with a high range resolution, speed, high resolution, wide speed range, the target of multiple images can be obtained anti-interference ability, than the size and weight of microwave radar and small. However, the laser radar technique is very difficult, not yet mature, and performance in bad weather, so the application subject to certain restrictions. Laser radar is still a developing technology, some laser radar system has been useful, but many laser radar systems are still developing or being explored. Laser radar type can be divided from a different perspective.

Pleased to see that a group of returnees, Dr. determined to come back, creating a fiber laser Wuhan Rui Branch, Xi'an torch light and other companies, R & D production of high-power fiber lasers and diode laser pump source, believed to have independent intellectual property rights 4KW continuous wave fiber lasers will soon will be presented in front of people. Laser drilling: mainly used in laser drilling of aerospace, automobile manufacturing, electronic equipment, chemical and other industries. The rapid development of laser drilling, mainly in the hole with an average output power of YAG laser has been 5 years ago, a 800w to 400w to 1000w. The relatively mature domestic laser drilling applications in man-made diamond and natural diamond drawing die and watch the production and instrumentation of the jewel bearings, plane blades, multi-layer printed circuit board manufacturing industries. Lasers currently used mostly YAG laser, CO2 laser-based, there are some excimer lasers, isotope lasers and diode-pumped lasers. The manager is showing the smooth working of  laser pointer .
Laser heat treatment: widely used in the automotive industry, such as cylinder liner, crankshaft, piston rings, commutator, gear and other parts of the heat treatment, while in the aerospace, machine tool industry and other machinery industry also widely used.

laser cutting can be replaced by the completion

these high strength, high absorption of laser light is also only applies to clear the hard tissue. The joint venture of laser pointer has high production ability. The manager emphasizes safety of laser pointer. The subcontractor of laser pointer takes great responsibility. Laser in industry, but also wide range of applications, because the laser in the laser beam is focused to the surface when the material melts, the laser beam and the material for the relative motion along a certain path, to form a certain shape of the kerf. Seventies, in order to improve and enhance the quality of flame cutting incision, but also to promote the ethylene oxide precision flame cutting and plasma cutting. In industrial production in a certain scope. The use of laser in the beauty industry more widely. Laser is to produce high energy, focus precisely, a certain penetration of monochromatic light, the role of human tissues and locally produced high heat to achieve the removal or destruction of the target organization's purpose, laser pulses of different wavelengths to treat the types of vascular and pigmented skin, such as nevus of Ota, port wine stains, freckles, age spots, telangiectasia, as well as to tattoo, eye line, eyebrow, scar treatment, etc.; In recent years some of the new laser, high-energy ultra-pulsed CO2 laser, Erbium laser for wrinkles, skin resurfacing, treatment of snoring, teeth whitening, etc., and achieved good effect, for the laser surgery to open up more and wider area. The incoming test of laser pointer  matters a lot.
Laser surgery can not be compared with the advantages of traditional surgery. The first laser surgery does not require hospital treatment, a small incision, intraoperative not bleeding, trauma light, no scar. For example: bags under the eyes of traditional surgical method of treatment because there is a wide range of spin-off, bleeding, slow healing after surgery, scarring and other shortcomings is easy, and the application of ultra-high-energy pulsed CO2 laser treatment of bags under the eyes, places it does not intraoperative bleeding, No stitching, does not affect the normal operation, the surgical site edema, light, quick recovery, no scars, etc., so that conventional surgery can not be compared. Some bleeding can not be because of endoscopic surgery, laser cutting can be replaced by the completion. (Note: There is some scope to adapt). Vascular laser treatment of skin and pigmentation in the efficient and effective delivery.

the diagnostics of laser diode

For this reason, scientists have used a liquid crystal laser beam into the separator 200 can be individually controlled a small laser beam, researchers can control the laser beam so as to form a triangle, quadrilateral, pentagons and hexagons and other shapes, thus moving large groups of nanotubes so that they locate in the surface of a microscope slide, to achieve the purpose of moving carbon nanotubes. The success of the optical capture technology by the University of California nanotube experts, physicist Alex ? Ze Teer praise, he said, because there is not a reliable technique to manipulate a large number of nanotubes, which kinds of new optical capture technology has the potential for industrial. Laser applications in medicine is divided into three categories: Laser Life Science, laser diagnostics, laser treatment, laser treatment is divided into: laser surgery, laser bio-stimulation of the weak non-surgical laser treatment and photodynamic therapy. The joint venture of laser pointer has more than one hundred employees.
Used in dental laser dental laser system based on the different roles of the application is divided into several different laser systems. Distinction is an important feature of the laser: the wavelength of light, different wavelengths of laser on the role of different organizations in the visible and near infrared spectral range of light absorption is low, penetrating and strong, can penetrate into the tooth structure more deep parts, such as argon ion laser, diode laser or a Nd: YAG laser (Figure 1). The Er: YAG laser and the CO, laser light penetration is poor, can only penetrate the tooth structure about 0.01 mm. Difference between the two lasers is an important feature: the laser intensity (ie, power), as applied in the diagnostics of laser diode, the intensity of only a few milliwatts, which is sometimes used in shock. For the treatment of the laser, usually a few watts of moderate-intensity laser. Laser organizations, and also depends on the laser pulse emission mode, the typical way a continuous pulse laser emission are: argon ion laser, diode laser, CO2, laser; to launch short-pulse laser are: Er: YAG laser or many of the Nd: YAG laser, short pulse laser intensity (ie, power) can be up to 1,000 watts or more.

Laser skin care section of the application

The customer is satisfied with the quality enhancement of laser pointer . As the laser light is still on normal tissue damage, so the amount of each laser treatment should not be too large, so as not to damage the excessive formation of scar, should adopt the Deep sub-sub-treatment methods. After treatment, the destruction of the pigment is absorbed, so the use of laser treatment of skin pigment disorders can not be anxious for a short time after treatment has no effect do not have to worry. Laser in the treatment of diseases more and more, for many diseases, scalpel or laser is nothing more than an alternative to other existing treatment tool; and for other diseases, the laser treatment does represent a revolutionary progress. Previous treatment of these diseases are often very unsatisfactory, or even do nothing, the laser can not solve these problems a new answer. Laser skin care section of the application, especially in recent years treatment programs, most of the latter, for example, wine stains, telangiectasia, rosacea and other superficial vascular diseases, Ota, coffee, milk spots , freckles, superficial pigmented congenital nevi and other congenital diseases, and age spots. The company will hold the design liaison meeting of laser pointer  with the end user.
Part of the treatment of acquired pigmentation and excessive body hair, artificial or superficial traumatic tattoo tattoo removed, the laser in these areas have become the preferred method of well-deserved, this is a benefit both patients and the revolution, the number of For millennia, mankind has never been so free, fast, effective and safe removal of those dreams too want to remove the unsightly disease. In addition, for superficial wrinkles, superficial scars, and many new directions, people will develop a more rational treatment. Therefore, the plastic surgeon needs to be more master these new treatment methods in order to go beyond the conventional skin grafting and other surgical methods for patients with better treatment. The design liaison meeting of laser pointer will be held again next week. All the technical personnel are required to take part in the design liaison meeting of laser pointer . Laser light is known as magical reputation. Laser cosmetic skin specialist after decades of clinical experience and practice, it is becoming much people welcome medical beauty. The greatest advantage of laser Beauty: Laser treatment of various skin conditions can be completely comprehensive repair skin texture, you can achieve double benefit purposes.

the use of laser resurfacing technology

The biggest advantage of laser cutting is the incision, less bleeding, clear operative field. Currently used super pulsed laser, the laser energy emitted together, and through a special switch to energy release in an instant, powerful energy gasification will be organized quickly, cutting not only fast, but also around the incision to minimize heat transfer, the incision minimal surrounding tissue injury. For double eyelid surgery, eyelid surgery, face lift, and achieved good results. Laser resurfacing, the use of laser resurfacing technology, which works by changing the focusing properties of the laser, the laser points into a spot, re-use pattern generator, the spot in accordance with certain graphics scanning the laser spot generated in an instant heat within the scope of the scan to remove the target tissue. Each spot intensity, density, shape and size of the scan by the computer control to accurately control the depth of the target tissue removal, for therapeutic purposes. Laser resurfacing is not only easy to overcome the traditional method of bleeding, difficult to control the depth of shortcomings, as well as to stimulate the skin elastic fibers to shrink role. The packing list of laser pointer contains a lot of information.
Contraction of the elastic fibers to tighten the skin, to further promote superficial wrinkles disappear, wrinkles more evident. During laser resurfacing before and after surgery should be dark, appropriate vitamin drugs, medication or medication to prevent postoperative facial infection. Occasionally, surgery skin pigmentation of the skin will appear in yellow are more common. Within three months after the high incidence of pigmentation, this pigmentation and more disappear in six months, no recurrence. This happens, do not have special treatment, should be dark, and under the guidance of a doctor using some skin care products. To avoid permanent pigmentation, the choice of surgical indications should pay attention, try to choose light or dark skin color of patients, for the color used with caution in between skin surgery. Laser treatment of facial capillary hemangioma, nevi and so on. The principle is that the organization of different colors for different wavelengths of laser absorption rate is different when using these specific wavelengths of laser irradiation of the lesion, these pigments, or hemoglobin, the most important by laser damage, and damage to surrounding normal tissue by the minor, when destruction of the diseased tissue is gradually absorbed by the body, disease, or skin pigment will be cured.

Thin-layer lamination manufacturing

Science and Technology Development Co., Ltd. Wuhan bleomycin developed a cyclone CO2 laser, shown in Figure 1, the rotation of the gas flow to a new way to make swirling axial flow CO2 laser also has a CO2 laser beam quality and cost of cross-flow CO2 laser low, the advantages of small size. The industrial promotion and application of laser processing, laser processing industry in China will be the development and popularity play a positive role in promoting. Three-dimensional optical shape (StereoLithographyApparatus, referred to as SLA) process is the use of ultraviolet laser beam scanning light-curing adhesive layer by layer method to form three-dimensional solid workpiece. In 1986 the company launched a commercial U.S. 3DSystems prototype SLA-1. SLA process to achieve the highest precision 0.05mm. Thin-layer lamination manufacturing (LaminatedObjectManufacturing, referred to as LOM) process uses thin materials such as paper, plastic film, etc., by the United States Helisys developed in 1986. By repeated CO2 laser cutting and pasting material, the workpiece to be layered manufacturing entity. LOM process is characterized by large-scale manufacture of parts for its accuracy 0.1mm. The enterprise management of laser pointer company should be in accordance with the stipulation.
Selective Laser Sintering (SelectiveLaserSintering, referred to as SLS) process is the use of powder-like material formed by the University of Texas at Austin in 1989 and developed through the use of high-intensity CO2 laser layer sintering materials to selectively scan powder to form three-dimensional parts, SLS biggest advantage of the selection process more widely. The three laser rapid prototyping technology as the development of a long time, technology is relatively mature, at home and abroad have been more widely used. However, the above method to form the three-dimensional parts can not be directly used as a mold, the need for follow-up, so I called the indirect laser technology into a mold. The main treatment methods are: rapid prototyping parts treated as a mold. LOM paper mold made directly by the surface treatment of wood instead of sand casting mold.

to three-dimensional shape.

With the development of laser technology, now people are starting to use in some processing applications, high-power fiber lasers and high-power semiconductor lasers. Nd: YAG laser material for solid-state laser work of Nd: YAG rod, the laser wavelength of 1.06μm. Since this type of laser for laser conversion efficiency is low, by both volume and thermal conductivity of YAG rod limit, the laser output average power is not high. However, Nd: YAG laser through the Q-switched laser output of the compressed pulse width, pulse work in order to obtain high peak power (108W), for applications requiring high peak power laser processing applications; its another big advantage is transmitted through the optical fiber, optical transmission to avoid the complexity of the design in 3D processing is very useful. The profit of this kind of laser pointer will be tremendous for the large market need.
In addition, the third harmonic technology can also be converted to the laser wavelength 355nm (UV), laser technology has been applied to three-dimensional shape. CO2 lasers work the material into CO2 laser gas mixture, the main applications of the laser wavelength of 10.6μm. Since this type of laser for laser conversion efficiency high, while the heat generated by the laser work can be spread rapidly by convection or delivered to the laser gain region, the average power output of the laser can be a very high level (million watts or more) to meet high-power laser processing requirements. Home and abroad for laser processing power CO2 laser, mainly cross-flow, axial flow lasers. ① cross-flow lasers: cross-flow laser beam quality is not good for multi-mode output, mainly used for heat treatment and welding. China has been able to produce a variety of high-power transverse flow CO2 laser line can meet the domestic demand for laser welding and heat treatment. ② axial flow lasers: axial laser beam quality is better, the base for the fundamental mode or quasi-mode output, mainly for laser cutting and welding, laser cutting equipment market in China mainly occupied by foreign axial flow lasers. Although the number of axial flow lasers laser manufacturers in foreign countries to do a lot of work, but need to import the main parts, a significant decline in product prices is difficult, with low coverage. The accessory of laser pointer will be packed in the package box.

laser cladding technology

In the production line, the laser cutting robot parts for metal forming has been online three-dimensional cutting. Efficient application of laser cutting systems, significantly reducing development time for new cars and car production preparation period, the production of automated and flexible. According to reports, the car manufacturing laser cutting than traditional machining methods of processing costs reduced by 50%, and production efficiency has been greatly enhanced. Can be expected, as consumers increasingly personalized vehicle pursuit, a small quantity and variety will inevitably become the trend of car manufacturers, and with technology, continuously improving the quality of laser cutting systems, prices have dropped, laser cutting technology will automobile industry to get more widely used. The complete implementation of personnel responsibility of laser pointer is very important.
In addition, the auto industry also uses the laser welding, laser surface modification, laser detection, laser rapid prototyping, laser texturing technique, laser cladding technology, and various types of laser technology. Ships with a laser range finder, laser in the Navy's most successful and most important applications, his main and TV tracker, IR tracker and optical fire control system composed of a large computer. The fire control system can be in small ships as the main fire control, in large ships can be used as auxiliary fire control system. Out of surface warships with a laser range finder, submarine periscope also used the laser range finder, we can see, the laser ranging technology is more mature in the military on the use of an example. Some specific technical details of laser pointer need to be confirmed during the meeting. Best Production Month of laser pointer. A minute of laser pointer will be formed by two parties at the end of meeting. However, the use of lasers in the military is the most sophisticated laser-guided weapons, such as laser-guided missiles, laser-guided bombs, laser-guided bombs, laser-guided torpedoes and so on. Laser-guided missile consists of three parts: the seeker, warhead, tail. Laser-guided missile and not a laser, mainly laser. Laser and is not installed in a missile, and its role in launching two planes: one is called laser machine, a missile carrying machine.

laser cleaning technology is a green cleaning process

by regulating the laser process parameters, you can not damage the substrate surface, based on the effective removal of different types of surface contaminants, such as the new addition to a clean surface, the laser can also be easily cleaned to automate, in line with smart printing; laser cleaning equipment can be long-term use, usually require only electricity and maintenance costs, long-term use of the operating cost is relatively low; laser cleaning technology is a green cleaning process, basically do not cause pollution to the environment. The technology import of laser pointer has been arranged in the schedule.
The technology also is expected to be applied within the domestic rolling aluminum surface grease pit cleaning, suitable for PS plate or CTP plate production line of aluminum pretreatment. Laser applications in the automotive industry: the automotive industry, the laser cutting process is usually based. Laser cutting is generally low-level model using the base model or high power, laser beam has been focused by a high power density, melting or vaporization can produce material phenomena. As the metal surface for the wavelength of the CO 2 laser 1016L m high reflectivity in order to increase cutting speed and cutting quality, cutting metal parts are often blowing oxygen or compressed air, in order to improve cutting efficiency, while cutting flammable materials are blowing nitrogen other inert gas to prevent burning. Laser cutting has many advantages: sewing narrow (011mm ~ 015mm), to save material; workpiece thermal deformation is small; only without clamping positioning, marking, mechanical stress and the surface of the workpiece without damage; to cut brittle materials, and very soft , extremely hard materials, including hardened steel; incision parallel to the good, clean trimming, can be directly used for welding; high cutting speeds (up to 10m? m in the above), no tool wear; easy to implement numerical or computer controls, and multi-site operation. The worker is showing the maintenance process of laser pointer  to the customer.
Modern laser cutting technology has been developed into a complete laser cutting systems, in addition to power, a good laser modes outside the table comes with high-precision ball screw drive, the computer-controlled, multi-axis can be achieved through a variety of complex plane or space graphics of the cut, and even developed a higher precision, flexibility and better laser cutting robot. In many foreign automotive companies, laser cutting technology is very common. If the prototype development and small batch production, often use more than three-dimensional laser cutting systems, cutting of panels.

Glass lenses have long-term use

They promote the accuracy and convenience of the host and the audience.The lecturer and teacher with a laser pointer to demonstrate every day.It is also effective for the classroom or any auditorium. It is important to note, you must always like a reliable web site to buy the pointer you choose.Reliable web sites to ensure correct quality at the right price. As a tidbit, remember that a good quality pointer infrared filter, in order to avoid any damage to the eyes and the appropriate power level.Glass lenses have long-term use. Laser pointer safety is your dog? Is the laser pointer safe use and dog training or competition? Some dogs have a serious "forced" type of behavior (referred to as "stereotypie") when allowed to chase points from the laser pointer, but others do not develop these behavior.So, how do we know that our dogs may develop a stereotypie when exposed to a laser pointer, is only dangerous our dog's eyes?
Some varieties seem to be more inclined to the development of abnormal behavior when exposed to a laser pointer, but these varieties are also very popular as service dogs and many have been trained as a "goal" of a laser point no abnormal behavior in their work.So, although some people say, some varieties should not be allowed to play the laser point, it doesn't mean you're a particular breed of dog will develop a stereotypie.On the contrary, it does not mean just because you don't have a dog one breed of dog is safe, either.
Some signs, a stereotypie may develop in: -- open or catching area / s was last seen the place for more than 1 minutes. -- patrol the area / s, last seen for more than 1 minutes ago -- repeatedly returned to the area / s has seen it is without rhyme or reason. In addition to chase the point again -- development powerful chasing behavior of other sources of light or shadow
If your dog shows any signs of the above, then it is time to stop using the laser pointer as your dog may develop a severe behavior problems.You should find an experienced animal behaviorists if using a laser pointer is very important, your training objectives. Strongly recommend that you not use a laser pointer and play games with your dog.Almost every dog would like to chase the laser point, but it is not worth the risk.

the emission of light propagation in one direction

If you do a free pulse waveform, the probe attenuation to add one to three layers of paper; if it is Q-wave, the attenuation of the probe front of the paper than do the more free pulse (to do with lens cleaning paper, attenuation paper). When the measured waveforms are done, do not forget to switch off the probe. Ordinary light is light in all directions. Make the emission of light propagation in one direction, you need to light a certain condenser fitted with devices such as car headlights, and searchlights were installed on the role of the condenser mirror, so that radiation is to bring together in one direction injection. Laser emission of the laser, born in one direction injection, beam divergence is extremely small, only about 0.001 radians, nearly parallel. In 1962, the first human use of laser irradiation the moon, the moon's distance from the Earth about 38 million km, but the laser spot at the lunar surface less than two kilometers. If condenser works well, seemingly parallel light beam searchlight shooting the moon, according to its spot diameter will cover the entire moon. The  laser pointer  company manages to attract more customers with the low cost and expense.
Before the invention of the laser, artificial sources of high-voltage pulsed xenon lamp brightness maximum, comparable with the brightness of the sun, while the ruby laser laser light, xenon lamp can exceed several hundred billion times. Because the laser is extremely bright, they were able to illuminate distant objects. Ruby laser beam emitted illumination produced on the moon is about 0.02 lux (light intensity units), the color red, visible laser spot. If the most powerful searchlight with power moon light, the illumination produced only about a trillionth of Lux, the human eye can not detect. The main reason is the high brightness of laser light directed. A large number of photons concentrated in a very small space within the injection, the natural high energy density. Laser intensity and the ratio between the sun is one million, and it is a human creation. Color of the laser depends on the laser wavelength, the wavelength depends on the laser active material issue, he incurs the laser stimulation can produce the kind of material. Stimulation can produce deep pink ruby laser beam, it is used in medical applications, such as for skin treatment and surgery.

laser pointer has some obvious merits

Phenomenon: the semiconductor laser is not bright red indication. Cause: The battery power, frequent contact with the semiconductor laser bad or worse. Remedy: In practice, laser removal of the old instructions, and replaced with regulated power supply of the semiconductor laser is better. The customer is a member of this  laser pointer  website.
Special attention: JSY-01-type pulsed Nd: YAG laser radiation is very high laser power, the process a little careless with the laser will damage the body or goods. Ranging from burn clothing, skin burns, eye weight is causing permanent blindness, so the instrument starts, allowed to look into the laser cavity, the absolute prohibition of direct or reflected laser injected into the eye, the officer should wear laser protective glasses; If exposure to combustibles on the fire. In addition, the laser pump power, and Q-trigger circuit using high-voltage power supply, accidental contact can cause personal injury. Phenomenon: in the case of intact probe could not be determined oscilloscope waveform. Reason: The inappropriate use of the pulse type. Probe than the right. The  laser pointer market is already built. This kind of  laser pointer  has some obvious merits. Remedy: Check the type of pulse used, the general use of pulse type edge, to select rising edge or falling edge. Click the channel used, the probe ratio of 10:1. Phenomenon: a single pulse on the oscilloscope single key pressed, run / stop key is always red, oscilloscope graphics flashed. Reason: small level. Remedy: appropriate level of transfer will be large, so that the waveform can be stopped. Phenomenon: the probe to detect the signal. Reasons: the probe circuit board Weld, together with the wire is too long. Remedy: According to the circuit, the number of discrete components required for welding into the probe. Soldering iron components, welded components have to be strong, not Weld, the best pin photodiode with a wire connected with the circuit board, which helps to protect the photodiode, a good soldering circuit boards to be clean, the wires used to is short. After welding should be debugging. The low cost and expense of  laser pointer  is very attractive.
YAG laser at the receiving probe laser beam emitted when the laser beam energy should be about 4%, that is out of the laser perforation at the receiver with a frosted glass, frosted glass on from the 15-20 point range to reflect the probe,

the interaction with the surrounding gas

Most of the arc is burning between electrode and workpiece arc as heat source. In the formation of joints, may or may not use filler metal. Electrode is used in the welding process the welding wire melts, the melting polar arc called, such as arc welding, submerged arc welding, gas shielded arc welding, tubular wire arc welding, etc.; electrode is used in the welding process does not melt The carbide or tungsten rods, called non-melting polar arc, such as TIG welding, plasma arc welding and so on. Arc welding is arc welding method of early development is still the most widely used as a welding method. It is coated with a coating of the external electrodes and filler metal for welding, arc welding is the welding tip and the surface between the combustion. Coating in the arc under the action of one hand, can produce hot gas to protect the arc, on the other hand can produce slag covering the weld pool surface, the molten metal to prevent the interaction with the surrounding gas.  laser pointer of super high quality is of the higher cost and expense.
Slag is the more important physical and chemical reactions produce molten metal or alloy elements added to improve the weld metal properties. Arc welding equipment is simple, lightweight, flexible operation. Can be applied to maintenance and assembly welding seam in short, in particular, can be used for difficult to reach parts of the welding. Arc welding with the electrode applied with the corresponding most industrial carbon steel, stainless steel, cast iron, copper, aluminum, nickel and their alloys. Submerged arc welding is a continuous feed, as when the wire electrode and filler metal. Welding, the welding area covered with a layer of granular flux, under the burning arc in the flux layer, the wire tip and base metal partial melting to form a weld. Under the action of heat in the arc, on the part of the flux and molten slag metallurgical reactions occur with the liquid metal. Slag floating on the surface of the metal pool, on the one hand to protect the weld metal, to prevent air pollution, and physical and chemical reactions produce molten metal, weld metal of extreme and improve performance; the other hand, can make the weld metal slow Coolers. Submerged arc welding can be used to a larger current. Compared with manual arc welding, its biggest advantage is that the weld quality, high welding speed. The machining process of laser pointer is important to enhance quality of laser pointer .

the YAG laser welding device

When the metal begins to melt or vaporize the surface, its reflectivity decreased rapidly. Two metallic materials at room temperature laser absorption rate is generally below 20 ℃; when the metal temperature reaches the melting and vaporization produces branded point of the absorption rate of up to 40 ~ 50%; when close to the boiling point of up to 90% absorption rate. The working condition of laser pointer is good enough.
The absorption rate of the laser material and the material is proportional to the square root of the DC resistivity, and the laser wavelength is inversely proportional to the square root relationship. Angle of incidence greater the absorption rate is smaller. When the laser light perpendicular to the metal surface, the metal absorption maximum of the laser. But usually to protect the laser exit lens, the need to maintain a certain angle of incidence. For low reflectivity can be coated with a thin metal surface layer of metal powder, but both must be able to form alloys. Such as copper, gold, silver can cover the sharp thin layer, then the same penetration in the case of welding the energy required is about the original copper, gold, silver and required a quarter. Quality of the YAG laser welding device, the focus of the (spot size) is the optical path through the device itself precision coaxial output fiber and outgoing head of the imaging ratio to be guaranteed. Laser emitted when the focus falls just above the location of the work is zero. Defocus amount is zero distance from the focus away from this amount. Focus position than the position is called a negative zero defocus (focus down to internal parts), the distance is negative defocus amount. Instead, the focus distance value is less than zero is the amount of defocus. To obtain a larger penetration depth, focus position can be selected within a certain location on the workpiece, that is, using the negative defocus amount of welding. The fault status of laser pointer is the important reference index.
Pulsed laser welding, mainly heat melting manner. Laser beam directly on the metal itself, the depth of penetration is limited, and its conductivity depends on the material temperature coefficient (conductivity temperature coefficient of the penetration depth is large) rather than the size of the laser power. Arc welding is the most widely used welding method. It includes: manual arc welding, submerged arc welding, gas tungsten arc welding, plasma arc welding, MIG welding and other gases.

the use of all-optical fiber laser structure

China's production and development of devices for optical fiber unit, although very much, but the overall level of technology is weak, the optical communication into a valley, when the unit is basically only choice in the industry for bankruptcy or shut down production lines in two ways, unable to invested huge resources in energy research and development of optical devices, so when the rapid development of all-fiber laser optical devices made of energy, when the urgent needs of our country in this area is basically a blank. For our first unit in the development of fiber lasers, the face of the domestic situation, the development of all-fiber laser is basically no foundation at all, so the plastic lens focus end-pumped external cavity of the program to become a realistic choice. The manufacture requirement of laser pointer is very strict.
This structure is very close to the traditional solid-state lasers, fiber-optic technology, dependence on low, non-fiber optic technology to production. However, practice shows that only the use of all-optical fiber laser structure in order to fully reflect the overall consistency, integrity, harmony and matching, the use of fully demonstrated the advantages of fiber lasers, therefore, all-fiber structure of the program more in line with the nature of the development of fiber lasers law, so, in the world, all-fiber laser into the mainstream program has its inevitability. All-fiber lasers and fiber-optic laser technology requires energy technologies combine, to some extent, the optical fiber laser technology in the development of a large proportion, therefore, the energy-energy laser technology and the development of optical fiber laser technology is not or missing legs. At present, engaged in the development and production of optical devices unit is still mainly concentrated in the industrial chain of optical fiber communication among the few involved in energy laser technology, which is facing the development of our fiber lasers huge problems.

the final acceptance of laser pointer

Currently, the use of fiber lasers have been 2-3 m wide defend the output of the laser line, the band's output in the lower loss in the infrared communication has a potential value. Some technical problems have been put forward during the final acceptance of laser pointer . The maintenance of laser pointer is very easy to carry out. China's commercial fiber lasers now entirely dependent on imports, because we have not implemented the commercialization of optical fiber lasers and industrialization. Development of our fiber laser is not lagging behind, has several units in a row for more than 200W output power, but China's industrialization fiber lasers has lagged far behind. The following analysis of the industrial development of China's optical fiber laser reasons for delay. As mentioned earlier, the development of all-fiber laser requires five key technologies, it is easy to see that five key technologies in addition to diode-pumped lasers, the other four key technologies are all closely related with the fiber-optic technology, precisely, is the energy optical fiber technology are closely related. Optical fiber technology is based on the signal energy-based technology developed, and the signal is mainly for optical fiber communication technology services, therefore, the energy of laser and optical communication technology through the two optical fiber link of this particular medium, so that in the fiber development and production of optical devices and the unit can be deeply involved in both technology and become the core strength. The worker should pay attention to the specific requirement of laser pointer .
In the optical communication into a valley when the fiber laser to achieve a historic breakthrough coincides with the time, many foreign development of fiber optic devices in optical communication unit of production began to shift energy research and development of optical devices, to seek new opportunities to expand to survive space. Fiber laser energy into the development of these units has become an important force in the development of fiber lasers, fiber lasers for the development of new all made a great contribution.

The mechanism is often the most important measure of an enterprise competitiveness.  laser pointer has become the indispensable specific tool for the teachers, reporters, lecturers or business men.
The development of proprietary technology in the long practice of laser materials processing experiments summary of some industrial users to summarize certain industries regarded as particularly valuable, proprietary technology, especially in the long practice of laser materials processing experiments. Wuhan Skyflying laser company with its proprietary technology in the three-dimensional sculpture of the glass body of valuable. Wuhan Skyflying laser company, with its in vivo three-dimensional sculpture in glass processing technology, rapid in vivo three-dimensional sculpture market in domestic and international glass to dominate.

the organization of appropriate resources

Industry development targeting a potential demand for the industry research industry as a whole needs the details, for those aimed at a potential demand for the industry, solid research needs details of the industry as a whole, the industry provide the most suitable processing system. For example, laborers laser is steel rolling roll texturing industry to provide the most suitable processing system. For example, processing the first and only company. They learn by doing to deal with the first and only company. Them side-by-doing, while learning by doing and finally make it to get a higher profile in the domestic steel cold rolling industry, laser roll hair system in Jinan Iron and Steel, Kunming Steel steel cold-rolled industry with higher visibility. It is the indispensable and specific tool of laser pointer .
Laser roll the hair system in a good run of Jinan Iron and Steel and other companies, but also earned a good run of Tangshan Jianlong Iron and Steel, Chongqing Iron and Steel and other large steel companies, has earned the Tangshan Jianlong Steel Corporation's orders . At present, the laborers laser is intends to laser roll texturing projects as a new order of the Corporation.

Systems integration for industrial applications, the organization of appropriate resources, integrated processing system to meet market demand, industry-oriented applications, the organization of appropriate resources, integrated processing system to meet market demand, this demand of the processing system is the integration advantages.  laser pointer  was a kind of the relatively newly emerging thing or product.
With the increasingly fierce market competition among enterprises to seek product is the integration advantages. With the increasingly fierce market competition, the difference to curry favor with the different preferences of the user groups, product differentiation is bound processing system differences. Difference to curry favor with the different preferences of the user groups, product differentiation is bound processing system differences. User-oriented system integration will be a high value-added huge market, user-oriented system integration will be a high value-added of the huge market, and market barriers to entry are higher. Integration advantages of Wuhan laser companies not as a core advantage of the higher threshold. Apparent, the reasons are: industry research is not deep, only. In the past, the related study or research of  laser pointer  was not much domestically or internationally.

the equilibrium particle distribution contrary

Light through the work material, the light energy will only weaken not strengthen.  Laser Pointer  is especially used for computer mostly by the business man. To make the dominant stimulated emission must be made in a high energy level E2, the number of particles is greater than the number of particles in a low energy level E1. This distribution coincided with the equilibrium particle distribution contrary, called population inversion distribution referred to as population inversion. How technically to achieve population inversion is a necessary condition for producing laser. Theoretical studies have shown that the substance of any work, under appropriate excitation conditions, in particular between the high and low level of the particle system inversion. If the microscopic particles such as atoms or molecules with a high energy level E2 and low energy levels E1, E2 and E1 on the level of the population number density of N2 and N1.  Laser Pointer  is well received in America and Europe.
The existence of the spontaneous emission transition between the two energy levels, stimulated emission transitions and the three processes of stimulated absorption transition, etc.. By stimulated emission transitions generated by stimulated emission of light, with the same frequency, phase, direction of propagation and polarization direction with the incident. Therefore, a large number of particles at the same excitation of the coherent radiation field generated by stimulated emission of light is coherent. Monochromatic energy density by the stimulated emission transition probability and the stimulated absorption transition probabilities are proportional to the incident radiation field. When two levels of statistical weight equal to the probability of the two processes are equal. More technical details of Laser Pointer  should be determined as soon as possible.
N2, <N1 in the case of thermal equilibrium, so spontaneous absorption transition dominated by the light through the material, usually due to shock absorption and attenuation. External energy incentives can destroy heat balance N2, leaving> N1, this state is called population inversion state. In this case, the stimulated emission transition dominant. Light passing through a period of length l in the inversion state laser material (active material), light intensity increased eGl times. G is proportional to the coefficient of (N2-N1), known as the gain coefficient, its size and the nature of the laser material and the light wave frequency.

the consensus on the direction of propagation

This radiation process is called spontaneous emission. Many atomic spontaneous radiation emitted light does not have a phase, polarization state, the consensus on the direction of propagation, is mentioned in the physically non-coherent light. In 1917, Einstein's theory that: In addition to spontaneous emission of particles in high energy level E2 can also be another way to transition to a lower level.  Laser Pointer  is specially manufactured for the school.
He pointed out that when the frequency ν = (E2-E1) / h photon incident will give rise to particles with a certain probability. Quickly from level E2 transitions to the level of E1, while the radiation with external photon frequency, phase, polarization and propagation direction are the same photon, a process called stimulated emission. Can be assumed that if a large number of atoms in a high energy level E2 a frequency ν is = (E2-E1) / h of the photon incident, which inspired the E2 atoms generated by stimulated emission of radiation, the two features in exactly the same photon two photons to motivate the E2 level on the atom, to produce stimulated emission, can get the four characteristics of the photon, which means that the original optical signal is amplified. This process of stimulated emission and amplification of light is a laser.  Laser Pointer  can be easily bought in the market. The package weight of Laser Pointer is a part of the gross weight
Einstein's 1917 proposed by stimulated emission of radiation, lasers come out in 1960, separated by 43 years, why? The main reason is that ordinary light particles generated by a very small probability of stimulated emission of radiation. When the frequency of the light launched into the working substance, stimulated emission and the shock absorption of the two processes at the same time, subject to stimulated emission increase in the number of photons, while filling the number of photons by stimulated absorption decreases. Substances in thermal equilibrium, the distribution of particles on each level, follow the equilibrium statistical distribution of the particles. Laws of statistical distribution of the number of particles in the lower level of E1 must be greater than the number of particles in the higher level of E2.

common application of laser systems

Army land-based small-scale anti-missile laser system, the Air Force using airborne laser anti-missile system and the Navy used in carrier-based laser anti-missile system using the LD-pumped solid-state lasers [13].

High portability will enable the individual combat capabilities greatly improved, and give full play to the role of a soldier, of course, the idea is still only at the theoretical stage. Laser weapons toward the twin goals of development, of course, to achieve these two objectives need to wait for very long. Shown in Figure 7, for the future U.S. military vehicle laser weapons effect diagram [14]: the U.S. car laser weapons in the future renderings. Shown in Figure 8 [15] shown for the Northrop Grumman-developed high-power solid-state lasers, from the power of 100 kilowatts. All problems of quality control of Laser Pointer have been solved.
It can be said that this power solid-state lasers to high power directional development has taken a very meaningful and very important step. Figure 8 Northrop Grumman developed the high-power solid-state lasers. The laser processing is the most common application of laser systems. According to the mechanism of the laser beam interaction with the material, the laser processing can be roughly divided into two types of laser thermal processing and photochemical reaction processing. Laser thermal processing refers to the use of the thermal effects generated by the laser beam is projected onto the surface to complete the processing, including laser welding, laser cutting, surface modification, laser marking, laser drilling and micromachining; photochemical reaction processing refers to the laser beam exposure to the object, with the high-density high-energy photon trigger or control of the photochemical reaction process. The price negotiation of Laser Pointer is indispensable before achieving a good price of Laser Pointer .
Photochemical deposition, stereolithography, laser etching. We take a look at the processing and application of solid-state lasers. Laser cutting technology is widely used in the processing of metallic and nonmetallic materials, can significantly reduce processing time, reduce processing costs, and improve the quality of the workpiece.

annealing of semiconductor materials

The conversion efficiency is relatively low. Very low overall efficiency of the solid-state lasers, such as the ruby laser for about 0.5% to 1%, the overall efficiency of the YAG laser for 1% to 2%, 3% accessible in the best of circumstances. Some supplemental technical protocols will be signed in the design liaison meeting of Laser Pointer .
Visible solid-state laser efficiency there are a lot of space. The application of solid-state lasers. Extensive use of solid-state lasers in the military, processing, medical and scientific research. It is commonly used for ranging, tracking, guidance, drilling, cutting and welding, annealing of semiconductor materials, micro-machining of electronic devices, atmospheric testing, spectral studies, surgical and ophthalmic surgery, plasma diagnostics, pulse holography, and laser fusion . In the process of laser military applications, the solid-state lasers can be regarded as a rising star. Until the 1990s, due to the development of laser technology, solid-state lasers to cut a striking figure in a variety of military applications, and become the absolute protagonists. The supply manager of Laser Pointer should well know performance of Laser Pointer .
Conventional solid-state laser weapons. The laser range finder is the most commonly used laser systems in the armed forces, they are equipped with the main station tanks, artillery and infantry fighting vehicles, etc.. Equipment, you can greatly improve the attack hit rate. Compared to traditional optical sighting equipment, the hit rate several times greater. At present, the majority of military laser rangefinder 1.06mm neodymium-doped yttrium aluminum garnet (:) laser range finder. However, due to the long-term use of the solid-state laser is easy to damage Mask, are turning to 1.54mm erbium-doped (Er) for eye-safe phosphate glass laser. Of course, there are some extensive use of conventional laser weapons, such as a laser target designator (LD-pumped solid-state lasers), laser radar [12]. Quality of Laser Pointer will determine quality of Laser Pointer . All problems of quality control of Laser Pointer have been solved
Laser missile defense system. The laser missile defense or laser anti-missile basic characteristics are: by the speed of light, high-energy laser to destroy the speed of sound running of the missile or other flight solid. We can say in this regard is the LD-pumped solid-state lasers in the world, because it has some prominent advantages.

What is the secret to practice reading quickly steps?

1.Warm-up exercises soft focus:
A) the first time using your left hand, and your right hand, let six inches wide air -- (hypothetical), infinite symbols -- in space.Time: 60 seconds.
B) now close your eyes and the spirit of the visual production a narrow infinite -- a symbol of the page.Down time: 60 seconds.
C) pay attention to the eye movement pattern you can from left to right, right
Out of your sight.
D) to your RasterMaster or pen and Practice on a page, a sentence of the width, using Z for the Zorro strategy.Time: 60 seconds.
A soft consists of three elements:
One, pay attention to your eyes in the upper part of the letter words in each sentence.It is easier on your retina and increase your reading speed of up to 35%.
Second, the indirect word of the sentence, as if your eyes are binocular telescope; snailers focus on one word, as if their eyes are read by microscope.
Third, schizophrenia (separate), each sentence is divided into three terms of about three words each.Now use your RasterMaster or pen, to emphasize that every sentence is divided into three packages of about three words every.Continue to practice
Three block of two pages.
A hard focus
To really understand the execution is to compare it to the hard focus.When we read a word, watch TV, play video games, and use our word processor, we let our narrow focus is called hard.
It is also known as the narrow, like a horse and horse blinkers, used to eliminate what is transverse left, right side.Exchange our narrow eyes in conversation.

What is the laser hazard classification?

The laser has a broad power, need classification and specific safety procedures.Although the cold laser is usually used for non - invasive medical procedures constitute the minimum harm to the human body, the other lasers in the more powerful the scope of the current radiation and the danger of burns.Therefore, laser hazard classification system has been established.Based on the frequency of beam, laser hazard classification of service to ensure that when the need to take special care.To power and range, laser hazard classification?
Laser and their system by calling for a federal law that manufacturers have a classification.If it is a modification of a new task, it will need a new classification.Laser were assigned to 4 classes of 1, according to the possible biological damage.
Class I
Laser in this classification can not emit laser radiation in a dangerous level known.User class I laser usually exempt from radiation hazard control in the operation and maintenance.These lasers including your typical laser pointer or laser cat toys.
Class IA
This includes a special name for a 1000 second exposure based on.These are not in order to see if the supermarket laser scanner.For a class of IA emission is defined as a discharge is not more than the class I limits for a period of 1000 seconds.They did not cause harm, provide a contact beam is less than 1000 seconds.
Level two
These low power, visible laser issued the class I level, but not a radiation power is higher than 1 mW.It is assumed that the aversive response of human nature of light will protect a person.Therefore, the classification of specific control.
Class IIIA
This includes the intermediate drive those only regarded as a dangerous intrabeam watch.Limited control is applied to the classification.
Kind of hope
These include those with moderate power, without fire hidden trouble, but still be able to produce a dangerous diffusion reaction.Classification of the specific control requirements for their use.
Level Four
These are high power and harmful view under any condition.They also have the potential danger of fire, will damage the skin.This classification requires specific control their use.

The laser pointer is the best and convenient size

The laser pointer is the best and convenient size and does not require hands-free operation.
Astronomy
Green laser is the only color, should consider the astronomy.The number of required power vary depending on the person you will use.As a general method, the more people you and strong laser energy.Usually a 15 MW 35 MW is sufficient.As pointed out by hand and a laser pointer is the ideal.For installation in a telescope, a laser with a hands-free medium size is the best.
Combustion
For the combustion of common, such as lighting a match, cutting electrical tape, broken balloons, 95 - 125 MW power is more than sufficient.If the money is not a problem, you want to smoke, burning clothes and melt the plastic, you will need at least 150 - 200 megawatts of electricity.
Color is not a problem, because of high power laser can only be green.
Pointing out the door
A beam is clearly visible, in direct sunlight in a long distance, at least 55 MW power is wise.For some applications, such as alignment, laser and an on / off switch and efficient radiator is ideal
Non-lethal deterrence
For maximum effect and influence, at least 200 megawatts of power would be the ideal.Higher power will make the laser to stop people faster and longer range.In the tactical environment, laser portability is a problem and smaller as Sparta series is ideal.

How to buy a laser pointer -- Guidelines on how to buy the right laser do

Different types of lasers
Color
Laser is present in the red (632 nm), green (532 nm), and blue (473 nm), orange (594 nm) and infrared (808 nm to 1064 nm).Laser color determines the visibility of the laser beam and the price, attractive.Laser color uncertain laser energy.
Power
Laser power level measurement in mW which is an acronym mw.The range of available power from 1 kW to 400 mw.Power is a key factor in determining the possible application of laser and laser price.Power also determines the laser hazards.
Size
The size of the laser can range from a small size AAA battery the size of a baseball bat.The laser pointer is the two most common size on the laser pen size, portable laser small enough to fit in your pocket and larger hand size.
The on / off switch
The laser can be two types of switches, instantaneous opening or closing pressure switch and a standard Click to open or close the switch.Switch type determines the laser can be used or not.Many applications need to use laser is not free.
Safety features
Safety properties can range from zero to a fine range of keys, software dog, lens shutter and time delay.
Laser you deserve?
It all depends on what you want, laser your budget.
Demonstration
The blue and green laser is the best for the lecture because blue is the most impressive, is also the most expensive.A very important point and buy the demonstration of laser is power.Never buy laser power more than 5-10mW because the danger of your audience and your self.
