Laser mainly utilizes the photothermal effect when it interacts with biological tissue in cosmetology application, and the selective photothermal effect is the main principle of various laser cosmetic products at present. Selective photothermal effect is that biological tissues have special absorption properties to incident photons and causing limited tissue damage in the target tissue. By using the selective thermo-optic effect and selecting special wavelength laser to destroy the pigmented tissue structure and preserve the normal tissue, the therapeutic effect can be achieved, such as laser skin rejuvenation, laser freckle, tattoo removal, etc., human skin blue melanin absorption coefficient of 1064nm laser is larger.
The main components of device are:
The transmittable band of BBO is 350-4500nm. It is often used in frequency-doubled ND: YAG and other ND doped lasers, especially in low and medium power density lasers. The Q-switching method uses electro-optic Q-switching. Through the precise control of the external voltage, we can control the phase difference between the fast and slow light after the light passes through the crystal, so that the polarization direction of the output light changes. The BBO crystal is selected. It is characterized by a wide range of permeable bands and high efficiency of frequency doubling conversion.
