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.
