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.
