| Abstract: | A highly efficient 880 nm laser diode pumped actively Q-switched Nd:YVO4/BaWO4 eye-safe Raman laser is demonstrated. With an absorbed pump power of 10.9 W, 1.7 W of average output power at the Stokes wave-length is generated at a PRF of 40 kHz, corresponding to a diode-to-Stokes conversion efficiency of 15.6%. |
