Semiconductor laser has the characteristics of high-speed modulation, stable power, narrow line width, small size, compact structure and integrated drive circuit. Semiconductor lasers have excellent beam quality and modulation performance and are widely used in: scientific research, industrial instrument development, OEM system integration. In addition, pigtail semiconductor lasers, external fiber coupled modules, and small semiconductor pumped solid-state lasers are available.
Semiconductor lasers can provide scientific research or integration users with excellent-performance laser products for the manufacture of the most advanced laser systems. Semiconductor lasers have high photoelectric conversion efficiency and can be directly used in laser processing and other fields through beam shaping, while fiber lasers have become a hot research topic at home and abroad because of their excellent beam quality. But is it possible for semiconductor lasers to directly obtain high-beam quality lasers in the future, thus "beating" fiber lasers? In the case of increasingly tight energy, can the characteristics of high conversion efficiency of semiconductor lasers become more concerned?
The characteristics of semiconductor lasers are as follows:
1. The unique design of semiconductor laser: the use of multiple high-power single-tube laser series to replace the bar, eliminating the smile effect;
2. Comprehensive inspection: each single tube laser has been comprehensively tested, and there is a separate test report;
3. Burn-in test: rigorous burn-in test;
4. Strict selection: each pipe is singled out;
5. Series connection, series connection: damage to a single pipe does not affect the overall performance;
6. The power supply design is convenient: the use of high voltage low current power supply, easy to design, low price;
7. Passivation treatment: special passivation treatment process, greatly increase the service life;
8. Low power consumption: no power attenuation, semiconductor laser photoelectric conversion efficiency, low power consumption;
9. Semiconductor laser easy to cool, do not need micro-channel cooling;
10. Fiber coupling, easy to fiber coupling output.
