Passively Q-switched Nd:GYSGG laser operating at 1.3 μm with V:YAG as saturable absorber

The performance of a laser diode-pumped passively Q-switched Nd: GYSGG laser at 1331 nm with a V: YAG saturable absorber was first reported. A maximum average output power of 251 mW was obtained under pump power of 11.75 W. By using 8.8% output coupler, a minimum pulse width of 23.9 ns and a pulse repetition rate of 11 kHz were achieved, corresponding to the peak power of 954 W.
