A collimated double-sided cooling semiconductor laser system for medical cosmetology

Abstract

The invention provides a double-side refrigeration semiconductor laser system with collimation for medical cosmetology. The system is characterized in that linear light spots occur at a light outgoing part, thus greatly improving the light spots power density in working. The semiconductor laser system comprises a semiconductor laser array, a collimating mirror for fast axis collimation or simultaneously fast and slow axes collimation on light emitted by the semiconductor laser, an optical waveguide or a pair of light barriers coated with highly-reflective films at the inner sides, a transparent contact window adhered to a light outgoing port end of the optical waveguide, a pair of refrigerating blocks, and a first water through block, wherein the water through block is divided into a base part and a U-shaped head located above the base part; the middle part and back part of the optical waveguide are embedded in the U-shaped head; and the pair of refrigerating blocks extend toward the front part of the optical waveguide and enclose the side wall of the contact window and the front part of the optical waveguide. The semiconductor laser system adopts a special refrigerating structure design, so that the temperature of a working end face directly contacting with skin can approximate the freezing point, and the system is compact in structure and stable.

Description

technical field [0001] The invention belongs to the application field of semiconductor lasers, and relates to a collimated 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 worldw...

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.
