title: Compact high-power, TEM(00) acousto-optics Q-switched Nd:YVO4 oscillator pumped at 888 nm.
abstract: A compact, high-power, high-repetition-rate Q-switched laser oscillator is presented in this paper. Adopting the acousto-optics Q-switching mechanism, the maximum output power of 57 W of 1064 nm fundamental wave at 200 kHz is obtained under 110 W 888 nm pumping. The stable working range extends from 30 to 250 kHz, while the beam quality factor M(2) is smaller than 1.30. Subsequently, based on the 42 W of fundamental wave with the beam quality better than 1.10, 29.5 W of 532 nm green laser and 18 W of 355 nm ultraviolet wave are achieved.
