Two-side refrigerating type semiconductor laser system for medical cosmetology

Abstract

The invention provides a two-side refrigerating type semiconductor laser system for medical cosmetology, wherein a contact window of the system can be directly contacted with the skin. The two-side refrigerating type semiconductor laser system for medical cosmetology comprises a semiconductor laser device array, an optical waveguide arranged at the front end of a luminous surface of the semiconductor laser device array, a transparent contact window near to a light outlet end of the optical waveguide, a pair of refrigerating blocks and a first water passing block, wherein the first water passing block is divided into a substrate part and a U-shaped head part arranged above the substrate part, the middle part and the back part of the optical waveguide are embedded into the U-shaped head part, and a fixed block is arranged above the corresponding optical waveguide to fix the optical waveguide in a compacting way; and a gap is remained between the optical waveguide and the side wall of the U-shaped head part, and the pair of refrigerating blocks extend to the front part of the optical waveguide and pack the side wall of the contact window and the front part of the optical waveguide. According to the unique refrigerating structural design adopted by the two-side refrigerating type semiconductor laser system, the temperature of a work end face which is directly contacted with the skin can be enabled to be near to the ice point, and the two-side refrigerating type semiconductor laser system is compact and stable in structure.

Description

technical field [0001] The invention belongs to the application field of semiconductor lasers, and relates to a double-side cooling type semiconductor laser system for medical beauty. 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 performed worldwide in 2010...

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.
