The match or the material of laser pointer can be burned instantly
As of June 2002 on this laser industry of 200 enterprises (which laser product manufacturers 118 a, holographic products production factory 82) the statistics show that (this data does not include laser audio and video equipment, laser communications engineering, laser bar code detection and laser secondary benefits such as laser medical treatment, income, etc.): 2001 sales of laser products market of 3.24 billion yuan (including laser product sales of 2.839 billion yuan, holographic products sales of $ 4.01 billion), compared with 1.911 billion in 2000 Yuan increased 65.6%, a net increase of 1.253 billion yuan. 2001 laser products exported by the global economic downturn affect the annual export volume dropped to $ 24,690,300 from $ 40,455,000 in 2000, a decrease of 39%. The personnel is in charge of the raw material of the blue  laser pointer .
The main export products for optical communication, laser processing equipment, laser medical equipment and various types of lasers. It is predicted that 2002 laser products (including holographic products) total sales of up to 3.71 billion yuan. Laser processing equipment sales market is still bullish, laser medical equipment sales increased slightly in 2001, holographic security products sales in 2001, roughly flat to a slight increase in sales of holographic packaging materials there was a substantial increase , the optical component is affected by the impact of overseas markets, it is estimated that roughly flat sales in 2001. Laser products market in the world there was a substantial decline in 2001 to $ 5.6 billion from $ 8.8 billion in 2000, actually declined by 36 percent. And then material of  laser pointer  should be stored in the raw material area inside the workshop.
In contrast, despite the scale of the Chinese mainland laser products market is not large, but the technological innovation of the market demand, in recent years, laser product market size is not affected. Optoelectronic materials and their markets. Semiconductor optoelectronic materials, optoelectronic materials research has entered a stage of development of the application and industrialization. According to the 2002 China Electronics Materials Industry Association statistics show that the GaAs single crystal of the annual production capacity of approximately 600 kg. Research Semiconductor Materials AG and the China Electronics Technology Group Corporation 46 has been able to mass production for optoelectronic devices, GaAs, for example, is developing? 0mm low resistivity GaAs single crystal? 5mm GaAs single crystal. The worker should perform the manufacture, assembly and process of the blue laser pointer  in the specified area.
For LED and LD? 0mm of InP single crystal have been practical, the annual output of about 60 kg. For red, green LED GaP chip materials, annual production of about 90 kg, the vast majority of domestic LED market needs to rely on imports. Chinese monocrystalline silicon (Si) in 2000 produced about 400 tons, with a diameter? 00mm and? 50mm single crystal silicon-based.
