Semi-conductor laser system for laser medical beautification

Abstract

The invention provides a semi-conductor laser system for laser medical beautification, and a contact window of the system can be directly contacted with skin. The semi-conductor laser system for laser medical beautification comprises a semi-conductor laser array, a light guide which is arranged on the front end of a light-emitting surface of the semi-conductor laser array, the boss-shaped transparent contact window which is arranged on the light outlet end of the light guide, and a refrigeration block; the refrigeration block is divided into a substrate part and a hollow head part which is arranged above the substrate part; the front part of the hollow head part integrally joints and buckles the overall side wall of the contact window; a hollow sleeve with a high-reflective film plated on the inner surface is fixedly arranged in the cavity of the hollow head part; the front end of the hollow sleeve jacks the rear end surface of the contact window; and the light outlet end of the light guide is arranged in the hollow sleeve, and a gap is left between the light outlet end of the light guide and the hollow sleeve. According to the semi-conductor laser system for laser medical beautification, a unique refrigeration structural design is adopted, so that the temperature of a working end surface which is directly contacted with the skin can be close to a freezing point, and the structure is compact and stable.

Description

technical field [0001] The invention belongs to the application field of semiconductor lasers, and in particular relates to a semiconductor laser system for laser medical beauty 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 performed worldwide in...

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.
