Description

technical field [0001] The invention relates to a laser device, in particular to a hair removal device which uses a semiconductor laser to remove hair from the skin. Background technique [0002] Laser hair removal is based on the principle of selective photothermodynamics. By rationally adjusting the laser wavelength and beam, it penetrates the surface of the skin and is finally absorbed by the hair follicles containing more melanin. Through the selective absorption of laser energy, the hair follicles are damaged. , so that the hair loses its ability to regenerate without damaging the surrounding tissue. The laser hair removal effect is achieved by passing the laser of a specific wavelength through the epidermis. Since the process of hair follicle absorption and necrosis is irreversible, laser hair removal can achieve long-term hair removal effect.

[0003] In the prior art, Chinese Patent Publication No. CN2928026 discloses a patent titled "Portable Laser Hair Removal Device" of Enshi Laser Technology Co., Ltd., which is a hair removal device that users can carry with them; Chinese Patent Publication No. CN1452465 discloses a Japanese Ya A small power 5mW-1500mW semiconductor laser hair removal device named "Laser Hair Removal Device" by Mang Co., Ltd.; Chinese Patent Publication No. 2326182 discloses a device named "Long Pulse Laser Hair Removal Beauty Instrument" by Shanghai Laser Technology Research Institute Long-pulse laser hair removal beauty instrument. Among these hair removal instruments, the "portable laser hair removal device" of Enshi Laser Technology Co., Ltd. and the "laser hair removal device" of Japan Yaman Co., Ltd. have small output power, and the output energy is not accurate. Insufficient control; and the "long pulse laser hair removal beauty instrument" of the Shanghai Institute of Laser Technology adopts the voltage source chopping drive mode, so the energy output by the semiconductor laser changes with the change of the capacitor discharge current. The pulse dose of the laser source required to destroy each hair root is inaccurate, which affects the effect of hair removal and cannot achieve the purpose of permanent hair removal
