Abstract: A diode-pumped actively Q-switched eye-safe intracavity Raman laser with ceramic Nd:YAG gain medium and BaWO4 Raman crystal is demonstrated for the first time. The highest average output power of 0.76 W is obtained at a pulse repetition frequency of 30 kHz and a pump power of 11.3 W. The corresponding conversion efficiency from the diode pump power to Raman output power is 6.7%. The highest pulse energy of 38.1 µJ is obtained at a pulse repetition frequency of 15 kHz and a pump power of 7.8 W, and the corresponding peak power is 4.9 kW.

Abstract: A diode-end-pumped ceramic Nd:YAG laser discretely tunable for five wavelengths was demonstrated. The tunability was obtained by a blazing grating in Littrow mode, and the laser was discretely tuned from 1052 nm to 1073 nm. Under the diode pump power of 4.59 W, the average output powers at five wavelengths were all over 1 W. The laser source may find applications in spectroscopy and metrology.
