Diode side-pumped actively Q-switched Nd:YAG/SrWO4 Raman laser with high average output power of over 10 W at 1180

A diode-side-pumped actively Q-switched Nd:YAG/SrWO4 intracavity Raman laser has been demonstrated, in which a Nd:YAG module is used as the fundamental laser source and a SrWO4 crystal is used as the Raman active medium to generate first-Stokes laser at 1180 nm. A convex-plane cavity is employed to make the laser in a stable and efficient work under high pump power. At a LD pump power of 164 W and a pulse repetition frequency of 20 kHz, an average output power of 10.5 W at 1180 nm is obtained.
