Actively Q-switched intracavity frequency-doubled Nd:LuVO4/LBO green laser with an acousto-optic modulator

Abstract

This work presents experimental results concerning an actively Q switched intracavity frequency doubled Nd:LuVO 4 /LBO green laser with an acousto optic modulator operated at the wavelength of 0.53 μm. The green average output power of 2.8 W was obtained at a pump power of 16.3 W and a pulse rep etition rate of 20 kHz, resulting in an optical conversion efficiency of 17%. When the pulse repetition rate is operated at 5 kHz, the shortest pulse width and the highest peak power at 0.53 μm were measured to be 26.5 ns and 8.43 kW, respectively.
