According to the principle of laser light emission, it can be divided into continuous laser beauty instrument, active Q-switched laser, passive Q-switched instrument, dot matrix pixel laser instrument,
According to the light-emitting principle of laser beauty equipment, the class is divided into gas laser, solid laser, and liquid laser. Most of the lasers in the beauty industry are NdYAG solid laser and co2 carbon dioxide laser.
According to the luminous wavelength of laser beauty equipment, it can be divided into 532nm 1064nm 2940nm 10600nm super pulse laser and 1550nm mid-infrared laser
There is no so-called 550-1100nm wavelength laser, which belongs to the broad spectrum IPL and does not belong to the laser range
