Multi-wavelength high-power semiconductor laser light source system

Abstract

The invention provides a multi-wavelength high-power semiconductor laser light source system. The multi-wavelength high-power semiconductor laser light source system comprises a plurality of semiconductor lasers which output different wavelengths and are arranged in a centralizing manner, wherein the front ends of the light-emitting surfaces of the semiconductor lasers are in sealed and fixed connection with optical waveguides which can output laser beams after the laser beams are subjected to perfect reflection by the optical waveguides. According to the invention, lasers of the semiconductor lasers are outputted after the lasers are subjected to perfect reflection by the optical waveguides, each semiconductor laser can be individually controlled, and the wavelengths of the lasers are different, thus the outputted multiple wavelengths can have excellent uniformity; and in addition, the multi-wavelength high-power semiconductor laser light source system has the advantages of simple realization for process, high / low temperature resistance for optical components and parts, and greatly-enhanced and more reliable capabilities in resistance to shock and vibration.

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.

[0013] The patent with the publication number CN1498601A is a multi-functional laser beauty machine, which uses a solid-state laser as a light source and can only achieve output of two different wavelengths. will be very complicated
