ELECTRONIC SELECTABLE TWO-COLOR SOLID STATE LASER

摘要

An electronic selectable, two color solid state laser comprising a laser diode pump and a plurality of discrete optical elements disposed serially and sharing a common optical axis. The optical components include a laser rod of gain material having a laser emission wavelength, a polarizer cube, a means for compensating for OPO crystal polarization, an electro-optic active Q-switch having input terminals for applying a voltage across the Q-switch, and an OPO crystal. The laser rod has an input end face coated with an anti-reflector at the laser diode pump wavelength and a high reflector at the laser emission wavelength. The OPO crystal has an input end face coated with an anti-reflector at the laser emission wavelength and a high reflector at the OPO wavelength, and an output end face coated with a partial reflector at the laser emission wavelength and a partial reflector at the OPO wavelength.
