1064/532nm Nd:YAG dual wavelength laser can be widely used in the medical field. Nd:YAG lasers have high gain, low threshold, high quantum efficiency, and small thermal effects. 1064nm laser can be used for laser hair removal, and 532nm green light can be used for treating vascular skin lesions.
1064,532nm Dual Wavelength Laser
The working substance of Nd:YAG laser is a YAG crystal doped with a certain amount of Nd3+. The laser is a four-level system with an output wavelength of 1064 nm. Under normal operating conditions (room temperature), the 1064 wavelength laser is the most easy to start and has the strongest oscillation.
LN crystal has high nonlinear coefficient which makes it ideal for the production of integrated optics. The electro-optic Q-switched crystal and the laser crystal are driven by the same driving source, and when the voltage is applied, the state is low Q, when the voltage is removed,there is high Q state.
Mirror——M1, M2-Gaussian mirror. M5-output wavelength.
Electric machine——When a 1064nm laser is required, the LBO crystal can be controlled by the electric machine to move out of the optical path, and the fundamental frequency light is amplified by the Nd：YAG laser and directly outputted through the light guide arm. When a 532 nm laser is required, the electric machine controls the LBO crystal to move into the optical path.
The position of the LBO frequency doubling crystal is controlled by the electric machine, and the output wavelength of both 1064 nm and 532 nm is realized on one laser. Among them, 1064nm laser can be used for laser hair removal, and 532nm green light can be used for treating vascular skin lesions.
