Laser semiconductor laser system for medical beauty

Abstract

The invention provides a semiconductor laser system for laser medical cosmetology. A contact window of the semiconductor laser system can be directly contacted with the skin. The semiconductor laser system comprises a semiconductor laser array, a light waveguide, the a boss-shaped and transparent contact window and a refrigerating block, wherein the light waveguide is positioned at the front end of a light emitting surface of the semiconductor laser array; the boss-shaped and transparent contact window is positioned at the light-outlet end of the light waveguide; the refrigerating block is used for carrying out conduction cooling on the contact window, and is divided into a base part and a hollow type head part positioned above the base part; the side walls of the contact window are wholly attached and fastened by the front part of the hollow type head part; the light-outlet end of the light waveguide is positioned at a cavity of the hollow type head part, and a gap is left between the light-outlet end of the light waveguide and the inner wall of the hollow type head part; and the light waveguide is clamped and fixed by a pair of groove type fixed blocks, and the contact surfaces among the light waveguide and the fixed blocks are provided with gaskets which are hollow at the centers. The semiconductor laser system provided by the invention has the advantages that the unique refrigerating structure design is adopted, so that the temperature of the working end surface directly contacted with the skin can be close to the freezing point, and the structure is compact and stable.

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 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 were ...

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.
