Using a 808 nm fiber-coupled LD as the pumping source and an optimized-designed cavity, an end-pumped Nd∶GdVO4 laser is achieved. When the incident pump power to Nd∶GdVO4 is 20 W, as high as 11.3 W CW output at 1064 nm is obtained. The optical-to-optical conversion is up to 56.5%.Inserting an acousto-optic Q-switch, optimizing the size and the place of beam waist, the maximum Q-switched output is 9.2 W at the repetition rate of 30 kHz, and the peak power is 30.9 kW.Based on the experiment, a piece of KTP is used as the intra-cavity frequency doubling crystal, and a output of 6.3 W at 532 nm is obtained at the repetition rate of 30 kHz.
