Problems solved by technology

Even if there are a few multi-wavelength (3 wavelengths and above) lasers, they also generate lasers with wavelengths other than 1064nm and 532nm through an externally connected treatment handle with a built-in dye rod or titanium-doped sapphire crystal, which has low energy, short life, and poor spot quality. Unstable output and other shortcomings

Abstract

The invention relates to the technical field of medical equipment, in particular to a medical laser and a laser system. The invention provides a medical laser. The medical laser comprises a laser generating device, a frequency doubling device and a pulse width compression device, the laser generating device is used for outputting 1064nm Q-switched laser, and the laser generating device is arranged on a laser light path; the frequency doubling device is arranged at the output end of the laser generating device, and the frequency doubling device is used for outputting 532nm Q-switched laser; the pulse width compression device is arranged at the output end of the frequency doubling device, the pulse width compression device is used for generating 660nm-800nm picosecond laser, and the pulse width compression device comprises a lambda / 2 wave plate, a total reflection mirror, an output mirror and a titanium-doped sapphire crystal. The medical laser provided by the invention can realize the output of picosecond laser with the wave band of 660-800nm, and is large in output energy, good in light spot quality, stable in output and long in service life.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a medical laser and a laser system. Background technique [0002] The high incidence of pigmentation and the lack of ideal treatment has always been a major problem in skin beauty, and laser treatment provides an ideal treatment method for pigmentation. Laser freckle removal is different from traditional chemical or physical peeling methods. It uses a method that is less traumatic to the skin to fundamentally remove freckles, so it is safer and more effective. Lasers of specific wavelengths can selectively act on different skin tissues without affecting normal skin tissues. Laser energy can be absorbed by pigment particles in lesions in a very short period of time, generating extremely high temperatures, causing them to rapidly expand to form micro-blasts, which are vaporized and pulverized into very small particles, which are then absorbed by macrophages in th...
