After decades of development, laser technology has long moved from the laboratory to people’s daily lives. Whether it is clothing, food, housing, or industrial processing, and then to medical cosmetology, laser light is everywhere, affecting all aspects of people’s lives. From the development status of a country’s laser industry, the overall industrial manufacturing level can ...
High-power lasers usually generate large amounts of heat, which can easily damage the laser tube for a long time. It is not recommended to use high-power lasers for a long time. Figure 1. Withou the seat sink, can not work continuously for a long time Sometimes, the user needs to make the high-power laser work ...
An efficient laser-diode(LD) pumped Nd:YAG extracavity frequency conversion all-solid-state. quasi-continuous- wave(QCW) ultraviolet laser at 266nm was reported. The laser adopted LBO and BBO as the second and fourth harmonic generation crystals, and was pumped by three LD co nfig urations (high polarization LD, low polarization LD and low polarization LD with a Brew ster plate)in ...
Abstract: In recent years, the application of high-power semiconductor lasers has been expanding, and they are more and more widely used in industry and medical treatment. The thermal characteristics of lasers seriously restrict their reliability and service life. In order to improve the reliability and prolong the service life of the device,high power semiconductor laser bars with ...
