Output Wavelengths of Common Lasers?
This article details the different wavelengths emitted by various common lasers.
Wavelength of Lasers

If the 808nm semiconductor laser is divided from the output type: there is direct space output; fiber coupling output. It can also be divided into single-mode output or multi-mode output.
Semiconductor lasers are lasers that use semiconductor materials as working materials. Due to the differences in material structures, the specific process of different types of lasers is special. Commonly used working substances are gallium arsenide (GaAs), cadmium sulfide (CdS), indium phosphide (InP), zinc sulfide (ZnS), etc. There are three types of excitation methods: electric injection, electron beam excitation and optical pumping.
808nm semiconductor laser can be widely used in laser medical treatment, infrared night vision, laser printing, laser pumping, and various scientific research applications
Usually 808nm is used as a laser excitation source, the better Dilas, Nlight. But I recommend the former. What is the so-called industrial environment? Operating in an industrial environment? ? At present, 808nm 500W laser is used for plastic welding, which is a very good laser application.
