the semiconductor laser diode chip

Laser technology is the laser display industry, one of the main support conditions. This requires us to strengthen the development of laser technology, especially in laser technology breakthrough, because the laser will have a direct effect of the decision of the laser display. At present, China is still relatively lacking in this respect, any course is the main imports. Laser technology is another major investment in the support conditions. Laser display industry is a relatively long process of industrial development, long-term R & D investment is that many companies can not afford, so need the government investment in research funds for research and development. The only way to ensure that the field of laser technology research to move forward quickly. Laser display industry chain is very long, from the semiconductor laser diode chip R & D R & D production and then laser TV development, production spread to microelectronics, optical electronics, white goods, black appliances fields. Downstream industries which are the end product manufacturing industry (such as monitors, projectors and other equipment of the production), the upstream industry with the production of semiconductor devices. Greater efforts to promote the laser display industry will be able to bring a lot of high-tech industry. A new warehouse of laser pointer is under the construction. The production of laser pointer needs the guide of technical theory of laser pointer . It is reported that by 2000 the three major U.S. car companies 50% of the resistance spot welding line will be replaced by laser-welding production lines. 1995 World sales of laser processing system to account for the 1950 units, 640 units of which the United States, accounting for 34%. Mainly used in laser processing CO2 lasers and Nd: YAG laser. 58% in the U.S. for CO2 laser cutting, welding for 12%, 11% for the mark, 1% for the heat treatment, the other is 18%; Nd: YAG lasers for welding 24%, 39% for the mark, 7 % used for cutting, 18% for micro-machining, 3% for drilling, other 9%. In the medical laser, the United States is a world leader. Laser medical equipment is widely available not only in the United States, and a large number of exports, the United States, laser medical equipment by the U.S. Food and Drug Administration (FDA) unified management, and only approved registered before use and production, thus ensuring the products of laser medical equipment quality and reliability and security. The technical problems of laser pointer have been solved.
