Laser And Light Source Of Laser Hair Removal Machine

Laser and light source of Laser Hair Removal Machine:

When Laser Hair Removal Machine uses the principle of "selective photopyrolysis" to perform laser hair removal, the wavelength and pulse width of the laser should ensure that the laser hits the hair follicles without damaging adjacent tissues. Clinical studies have shown that the longer the wavelength of the Laser Hair Removal Machine, the deeper the penetration and the smaller the scattering, but the poorer the absorption of melanin, the more energy must be increased, but the epidermis cannot be damaged; the pulse width is smaller than that of the hair follicle. TRT (thermal relaxation time) is effective, and TRT larger than the epidermis is safe; the larger the spot size, the deeper the penetration; at the same time, active skin cooling should be used to protect the epidermis and relieve pain. When the wavelength of the Laser Hair Removal Machine is less than 600nm, the laser is mainly absorbed by hemoglobin and protein. When the wavelength of the Laser Hair Removal Machine is greater than 1100nm, the laser is mainly absorbed by the moisture in the body tissue. Light with a wavelength in the range of 600nm to 1100nm is transparent. Therefore, people usually use Laser Hair Removal Machine with a laser whose wavelength is in the range of 600nm~1100nm for hair removal. Laser Hair Removal Machine uses long-pulse ruby laser (694nm), long-pulse alexandrite laser (755nm), semiconductor laser (800nm), long-pulse Nd: YAG laser (l064nm), and high-pulse lasers and strong pulse light sources used for hair removal. Incoherent broadband light source (590~1200nm), etc.
