Semiconductor laser module for medical beauty

Abstract

The invention provides a semiconductor laser module for medical cosmetology. The module comprises a semiconductor laser array which is formed through overlying of a plurality of semiconductor lasers, optical waveguide which is arranged at the front end of a luminous surface of the semiconductor laser array, a boss-shaped transparent contact window located at the light-emitting port end of the optical waveguide and a refrigeration block used for conducting conduction cooling for the touch window. The refrigeration block consists of a base portion and a hollow head portion which is located on the upper portion of the base portion, the whole side wall of the touch window is attached and fastened by the front portion of the hollow head portion, a thermoelectric semiconductor refrigerator is arranged on the lower portion of the base portion of the refrigeration block, a gasket of which the center is hollow is arranged on the contact surface of the optical waveguide and a fixing block, and the base portion of the refrigeration block is coated with an insulation sleeve. By the aid of the special refrigeration structural design, the temperature of the working end face which is in direct contact with the skin is 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, in particular 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 wer...

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.
