Multifunctional laser therapeutic machine

Abstract

A multifunctional laser therapy apparatus relates to a multifunctional laser therapy device, which utilizes neodymium crystal with multi-passage transition property, and partially separates resonant cavity optical paths of laser with 1micron and 1.3 microns wavelengths. The multifunctional laser therapy device is characterized in that a 1 micron acousto-optic Q-switch is arranged in the 1 micron resonant cavity optical path, a 1.3 microns acousto-optic Q-switch is arranged in a common resonant cavity optical path of the optical paths with two wavelengths to control the laser with two wavelengths, switching on and off of the acousto-optic Q-switch is controlled by an extra signal generator, thereby achieving functions of optical switching and Q- adjusting, realizing six types of different output including two types of single wavelength continuous laser, two types of single wavelength Q-adjusting laser, double-wavelength quasi-continuous laser and double wavelength Q-adjusting laser, then one laser therapy apparatus device can output six types of output, thereby greatly widening application scope of the laser therapy apparatus device, and further, only one laser bar and one set of pump and cooling system are utilized, thereby saving cost.

Description

technical field [0001] The invention relates to a multifunctional laser therapy device.
