摘要

We report an intracavity Raman laser based on BaWO4 Raman conversion in a diode-pumped actively Q-switched Tm:YAP laser for the first time. With an incident diode power of 17.5 W and a pulse repetition rate of 1 kHz, the maximum average output powers of 880 mW and 306 mW for the fundamental laser at 1.94 mu m and the first Stokes laser at 2.36 mu m were obtained, respectively. The pulse width and pulse energy of the first Stokes laser were 14.1 ns and 0.31 mJ, respectively. The Raman gain coefficient of the BaWO4 crystal was estimated to be 1.1 cm/GW at 1.94 mu m.
