Abstract:

A passively Q-switched self-Raman laser emitting at 1178 nm is demonstrated with a c-cut Nd:YVO₄ crystal, using a Cr:YAG crystal as a saturable absorber. At a pump power of 5.0 W the maximum average output power of 540 mW is obtained, corresponding to an optical-to-optical conversion efficiency of 10.8%. Pulse duration of 10.8 ns, pulse-repetition rate of 42.5 kHz, and energy per pulse of 12.7 μJ are achieved when the pump power is 5.0 W. Interestingly, the second-Stokes component at 1316 nm appears when the pump power reaches 4.0 W.
