High Efficiency Passively Q-Switched Nd: YVO4 Laser Based on Cr4+: YAG Saturable Absorber
A compact V-shaped resonator structure was designed, and the 1 064 nm passively Q-switched Nd:YVO4 laser pumped by 808 nm diode laser was studied and stable Q-switched pulse output was obtained by using Cr4+:YAG crystal as a saturable absorber. The maximum continuous output power of 8.35 W was obtained at the pump power of 19 W corresponding to the light-to-light conversion efficiency of 44% and the slope efficiency of 56.4%. After inserting Cr4+:YAG crystal, the pulse output with an average power of 4 W, pulse width of 24.3 ns, repetition rate of 39.6 kHz, single pulse energy of 101 μJ, and the maximum peak power of 4.15 kW was obtained at the pump power of 19 W.
