.Diode-pumped actively Q -switched Nd: YAG laser at 946 nm[J].Optoelectronics Letters,2005,1(1):44-45 Diode-pumped actively Q -switched Nd: YAG laser at 946 nm YANG Ji-min LIU Jie JE Jing-liang [1]College of Physics and Electronics, Shandong Normal University , Jinan 250014, China Abstract:       A diode-pumped Nd: YAG acousto-optically (A-O)Q-switched laser at wavelength 946 nm formed with a simple plane-plane cavity has been demonstrated. The maximum average output power was 850 mW. The highest peak power was 531 W with the pulse repetition rate of 20 kHz and pulse width of 80 ns at the incident pump power of 19.5 W.
