摘　　要：采用脉冲激光二极管端面抽运技术开展了被动调Q人眼安全内腔式光参量振荡器的实验研究，研究了在浓度一定的Cr4＋：YAG调Q晶体下，基频光和信号光的输出能量和抽运阈值与输出镜透射率的关系，获得了输出能量8．5mJ，脉冲宽度2ns，发散角8mrad，重复频率20Hz的人眼安全激光输出，光光转换效率6％。A passively Q-switched eye-safe intracavity optical parametric oscillator, end-pumped by a pulsed laser diode array, is studied experimentally. The output energy and threshold of the pump wavelength and the signal wavelength with respect to the transmission of output mirror are analyzed at the same Cr4＋ ： YAG saturable absorber. The output energy of 8.5 mJ and the pulse widh of 2 ns at the eye-safe wavelength are obtained with the repetition rate of 20 Hz, giving the optical-optical conversion efficiency of about 6% from diode power at 808 nm to optical parametric oscillator （OPO） signal output.
