Abstract

As one of the primary products in the field of semiconductor lasers, GaAs-based semiconductor laser devices with an 808nm wavelength are widely applied in various industries such as industrial, medical, and scientific research. These devices possess substantial market potential. This paper reports on the development of a high-power array semiconductor laser device emitting at 808nm wavelength, achieved by our research team. At a temperature of 25°C, with a filling factor of 30% and an injection current of 50A, the maximum output power reaches 55.31W, and the photoelectric conversion efficiency is 58.74%. This device demonstrates exceptional emission performance.
