Diode-pumped eye-safe intracavity Raman laser with ceramic Nd: YAG gain medium and BaWO_4 Raman crystal

摘要

A diode-pumped actively Q-switched eye-safe intracavity Raman laser with ceramic Nd:YAG gain medium and BaWO_4 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 is 38.1 μJ 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.
