Abstract

The invention discloses a multi-wavelength laser, which comprises an Nd: YAG laser module, a frequency doubling module, a solid laser module and an output wavelength selection module. The fundamentalfrequency light emitted by the Nd: YAG laser module is used as pump light after frequency doubling by the frequency doubling module. The solid dye laser module comprises a resonant cavity and a soliddye block, and can generate pulse laser light of at least two different wavelengths under the action of the pump light. The output wavelength selection module can select one of at least four differentwavelengths of laser light for output. The output of laser light of four different wavelengths is realized on the same equipment, and laser light of more wavelengths can be output theoretically. Thedye laser part adopts a solid dye laser, which has the advantages of full curing, miniaturization, non-toxicity and low cost and maintenance fee. The output of laser light of multiple wavelengths is realized on the same equipment, the effect and efficiency of color tattoo removal can be improved, and cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a multi-wavelength laser. Background technique [0002] With the progress of society, due to the negative personal impact of tattoos, the number of patients who have tattoos removed is gradually increasing. The principle of tattoo treatment is to completely remove tattoo pigment without leaving traces or scars. Traditional tattoo treatments include electric burning, freezing, microdermabrasion and skin grafting, etc., but the effect is not ideal, often resulting in scars and changes in skin texture. [0003] Compared with traditional tattoo removal methods, laser tattoo removal has significant curative effect and obvious advantages. Laser tattoo removal is based on the principle of selective photothermal effect: as the target tissue, tattoo pigment particles selectively absorb the corresponding wavelength of laser light, and the laser pulse width is shorter than the thermal rela...
