Abstract
A diode-pumped acousto-optical(A-O) Q-switched extra-cavity frequency-doubled Nd∶YVO4/ KTP (KTiOPO4) green laser formed with a simple plane-plane cavity has been demonstrated. With the incident pump power of 12.7 W, A2O Q-switched average output power at 1 064 nm was 3.81 W with a duration of -5 ns at a repetition rate of 20 kHz, extra-cavity frequency doubling with KTP as the nonlinear crystal yielded the maximum output power of 1. 9- W at 532 nm, the corresponding optical conversion efficiency from 1 064 nm to 532 nm light is 50.4%. The continuous-wave(CW) laser properties of diode- pumped Nd∶YVO4crystal operating at 1 064 nm have been studied. With the incident pump power of 25 W, the maximum CW output power of 13.81 W was obtained with the corresponding optical conversion efficiency of 55.24%.
