According to LAS-CAD software,a compact laser diode (LD) dual-end-pumped acousto-optic Q-switched Nd:YVO4 laser is designed and optimized. In the experiment,an 808 nm fiber-coupled system and double concave face mirror folded cavity are adopted. The length of resonance cavity is 185 mm and the transmission of output coupler is 15%. A TEM00 mode output of 18.6 W is obtained under the condition of continuous waves (CW) at a pump power of 44 W,resulting in an optical conversion efficiency of 42.3%,and a slope efficiency of 47.8%,and M2 of 1.5. An 11.3 W of 1064 nm average power at a repetition rate of 100 kHz is generated with a 41 W LD as pump source,and an optical-to-optical conversion efficiency of 27.6% is obtained. The steady operation is achieved with pulse width of 25 ns,peak power of 4.52 kW and single pulse energy of 113 μJ at the repetition rate.
