Embodiment Construction

[0011] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0012] Nd:YAG crystal radiates 1064nm laser and Nd:YAP crystal radiates 1341.1nm laser to generate 593nm laser after nonlinear crystal and frequency, then 11 in the accompanying drawing is b-cut Nd:YAP crystal, the crystal 4 f 3 / 2 Towards 4 I 13 / 2 There are two spectral lines in the transition of , among which the 1341.1nm spectral line polarized along the c direction is stronger than the 1339.1nm spectral line polarized along the a direction. 12 is a xenon lamp for pumping, 13 is a filter tube to filter out the ultraviolet radiation of the pump lamp, 14 is a tight-packed elliptical or circular concentrating cavity, and 15 is coated with a 1341.1nm high-reflection film and a 1080nm anti-reflection film on the surface The total reflection mirror, 16 is a quartz polarizer placed along the Brewster angle, the surface is coated with an anti-reflection coating...

Abstract

The invention relates to a laser treating equipment whose emission wavelength is 593nm, 594nm, or 589nm which is near to ideal the absorption peak 577nm of oxidized hemoglobin, and since it is the full-solid laser treating equipment, compared to dyestuff laser, said treating equipment can significantly reduce the cost. The pulse length of output laser is 3-100ms which is continuously adjustable and each pulse can be divided into two or more 0.2-3ms long-pulse laser. Said long pulse laser treating equipment can replace present dyestuff laser treating equipment to treat the erythema lesion.

Description

technical field [0001] The present invention relates to laser medical equipment. Background technique [0002] Port wine stain is a type of birthmark, also known as port wine stain. The lesions are usually tight and intradermal, making them difficult to remove with conventional treatments. If the treatment is too shallow, the lesions cannot be removed. If you want to achieve the ideal treatment depth, you will definitely leave scars. The principle of isotope or X-ray treatment is similar. They all use the principle of radiation to treat lesions. Causes radiation damage which will be irreversible and eventually lead to scarring. In the case of PWS lesions, the target chromophore for laser therapy is oxyhemoglobin in intravascular blood. There are three absorption peaks of oxyhemoglobin: 418nm (blue), 542nm (green) and 577nm (yellow). Among them, 418nm is the maximum absorption peak of oxyhemoglobin. If we only consider the absorption capacity, the laser with this waveleng...
