Description

technical field [0001] The invention belongs to the application field of semiconductor lasers, and relates to a high-power semiconductor laser light source system, which is suitable for laser medical treatment. Background technique [0002] As an important field of laser application, laser medical treatment develops very rapidly and gradually matures. Semiconductor lasers are especially suitable for the manufacture of laser medical equipment due to their small size, light weight, long life, low power consumption, and wide wavelength coverage. [0003] Currently commercial laser hair removal systems include: ruby ​​laser (wavelength 694nm), emerald laser (wavelength 755nm), semiconductor laser (wavelength 810nm) and Q-switched neodymium-doped yttrium aluminum garnet laser (wavelength 1064nm). Among them, semiconductor laser hair removal has been proved to be a safe and effective way of laser hair removal. [0004] It is estimated that 5 million laser hair removal procedures...

AI Technical Summary

Problems solved by technology

The device uses a semiconductor laser with an output power of 5mW-1500mw and a wavelength of 600nm-1600nm for hair removal. Because the system output power is low, the spot size is small, and the wavelength output is not adjustable, the hair removal efficiency is very low.
