Countries in the economic growth mode transformation of high-tech industries, including direct financial support and policy support, and help to promote the development of the laser crystal materials production enterprises. China's rich rare earth resources is conducive to the expansion of production scale of the laser crystal materials. At present, nearly 90% of the laser crystal as the active ions, through the incorporation of rare earth and rare earth has become a very important element of a family in the laser crystal. Therefore, the development of the laser crystal material must do to ensure that sufficient resources of rare earth. China's rare earth reserves in the world, especially a relative shortage of heavy rare earth - in the military field, rare earth production accounts for 80% -90% of the world's rare earth the amount of commodities. These provide support for the development of the laser crystal materials industry in China. It is because of these advantages of the Nd: YAG crystal, which has been widely used in military, medical and other fields, has become a solid-state laser material the use of the laser crystal, and occupy the chief position of the laser crystal for 40 years. On the military side, the Nd: YAG crystal material as the most common solid-state lasers, has become a mainstay of military solid-state laser technology. High performance of laser pointer is required.
More than 90 percent of military solid-state laser Nd: YAG crystal as the working substance. In the field of medical science and the Nd: YAG laser medical equipment has also been a large number of applications. In the industry, because of Nd: YAG crystal to get high power laser output is widely used in materials processing, such as Nd: YAG laser processing of auto parts have been used by many of the world's car manufacturers. Yb: YAG crystal material. Yb: YAG crystal is an excellent diode pumped solid state laser materials with high doping concentration, high quantum efficiency, long fluorescence lifetime, the absorption bandwidth such. In theory, the Yb: YAG laser can be used as a laser weapons small and efficient laser source. For example, the 2 in 1 laser pointer will be described in the following.
Vacuum within three minutes reach 120torr, flashing numbers greater than 4090 to replace the flashing "hold" this leak than too large, the vacuum pump will stop. Repeat this process, if the leak is still too much than please contact the service department of the PRC Company. Within four minutes, the vacuum of less than 40torr and more of the same practice.
