Laser Application In Hair Removal
The principle of laser hair removal
Laser hair removal is based on the theory of selective photothermal action. The hair follicle and hair shaft are rich in melanin and the laser can target the melanin for hair removal treatment precisely and selectively. After the melanin absorbs the laser energy, the temperature rises dramatically, which leads to the destruction of the surrounding hair follicle tissue and removes the hair.
With the development of semiconductor laser technology, the products using VCSEL as the core device show many advantages, and have increasingly won the recognition and favor of global consumers in the field of laser beauty. At present, the mainstream hair removal instrument in the market uses 808nm laser as the core device.
At present, the market demand of semiconductor laser chip is strong, so it is of great significance to carry out independent research on semiconductor laser chip. LUMISPOT’s long pulse width vertical stack array uses high-density bar stack technology to provide multiple laser bar vertical stack packages with millisecond pulse width. The module adopts high efficiency heat dissipation design, macro channel water cooling structure (without deionized water), so that the module can achieve high brightness laser output while maintaining a small size.
