Optical active devices, passive devices, optical switching devices, integrated photonic devices; optical memory; high-power lasers. Laser market. According to incomplete statistics, China's current in the laser technology research unit of product development and production of laser applications is about more than 400 (excluding laser audio and video equipment manufacturing units), the perennial styling products production and sales and has a certain scale unit more than about 200, employing nearly 20,000 people. Laser professional Branch of China Optics and Optoelectronics Manufactures Association conducted the 2001 annual national laser product sales statistics show that. The acquisition of  laser pointer  should be done by the specific working personnel.Mainly used for integrated circuit (IC) and solar cells, of which about 250 300 t Si for solar cells, with an annual output power of about 4.5 MW. For blue LD and blue, green LED and GaN, SiC and other wide band gap semiconductor materials are being developed. Laser crystal materials in recent years, China's development of Nd: YAG and Nd: YVO 4 laser crystal.
