利用Nd：YAG电光调Q激光器抽运的1.064 μm高能量PPMgLN光参量振荡器（OPO）获得成功。在室温附近，当泵浦阈值为1.5mJ，斜率效率为30%时，获得了3.4mJ的最大输出脉冲能量。OPO输出信号波长为1552 nm，闲频波长为3384 nm。仔细观察了PPMgLN晶体输入表面的损伤，损伤阈值为4.6 J/cm 2。
A high-energy PPMgLN optical parametric oscillator (OPO) pumped by a E-O Q-switched Nd:YAG laser working at 1.064 μm was successfully illustrated. A maximum output pulse energy of 3.4 mJ was obtained with a pump threshold of 1.5 mJ and a slope efficiency of 30% around room temperature. The OPO output signal and idler wavelength were 1552 and 3384 nm, respectively. The damage to the input surface of PPMgLN crystal was carefully observed with a damage threshold of 4.6 J/cm2.
