【摘要】 An efficient diode-end-pumped actively Q-switched Nd:YLF/SrWO4 Raman laser is demonstrated.The fundamental wave is 1047.0nm and the corresponding first-Stocks wave is 1158.7nm.With a pumping power of10.5W,the average output power of 2.2W at 1158.7nm 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 8.7ns and the peak power is calculated to be 42.1 kW.The beam quaiity factors M2 in horizontal and vertical directions are 1.3 and 1.5,respectively.
