Semiconductor laser is a kind of laser developed in the 1960s, using semiconductor materials as working materials. Since the end of the 1970s, semiconductor lasers have clearly developed in two directions. One type is information-type lasers for the purpose of transmitting information, and the other type is power-type lasers for the purpose of directly using the optical power of the output laser. The working principle of the semiconductor laser is to use the excitation method of injection current to realize the electro-optical conversion of the electric energy of the injected current through the semiconductor material to output the laser. Semiconductor lasers can be used as pump sources for fiber lasers and solid-state lasers, and can also be used to make direct semiconductor lasers, which are used as light sources in materials processing, laser medical treatment, laser radar and other fields. The direct semiconductor laser is composed of a fiber-coupled semiconductor laser module, beam combining device, laser energy transmission cable, power supply system, control system and mechanical structure, etc., and realizes laser output under the driving and monitoring of the power supply system and control system.
With the rapid development and breakthrough of semiconductor laser technology, the quality, wavelength range and output power of semiconductor laser products are rapidly improving, and the product categories are becoming more and more abundant. They are applied to laser processing, 3D printing, lidar, life science and health, and infrared lighting and display. And many other aspects. High-power semiconductor lasers have the advantages of small size, light weight, high electro-optical conversion efficiency, stable performance, high reliability and long life. They have revealed their dominant position in the laser field and become the most promising field in the optoelectronic industry. One.
Semiconductor lasers are a type of lasers that mature earlier and are progressing rapidly. Because of its wide wavelength range, simple production, low cost, and easy mass production, and because of its small size, light weight and long life, its variety develops quickly and its application The range is wide, and there are currently more than 300 species. The application range of semiconductor lasers covers the entire field of optoelectronics and has become the core technology of today's optoelectronics science. Semiconductor lasers have been widely used in laser ranging, laser radar, laser communications, laser simulation weapons, laser warning, laser guided tracking, ignition and detonation, automatic control, detection instruments, etc., forming a broad market.
