Abstract An efficient diode-end-pumped actively Q-switched Nd:YLF/SrWO4 Raman laser is demonstrated. The fundamental wave is 1047.0 nm and the corresponding first-Stocks wave is 1158.7 nm. With a pumping power of 10.5 W, the average output power of 2.2 W at 1158.7 nm is obtained, with the corresponding optical conversion efficiency of 20.9%. At a repetition rate of 6 kHz, the pulse width of the Raman laser is 8.7 ns and the peak power is calculated to be 42.1 kW. The beam quality factors M2 in horizontal and vertical directions are 1.3 and 1.5, respectively.
