摘　　要：采用调Q Nd:YAG激光倍频光(0.532μm)泵浦温度调谐MgO:LiNbO_3晶体单、双谐振光参量振荡器(OPO包括DRO、SRO)的实验结果.双谐振(DRO)调谐范围达844.1～1411.3nm,最低泵浦阈值0.22mJ/pulse;单谐振(SRO)调谐范围达738.9～1032.2nm,最低泵浦阈值0.66mJ/pulse.最大能量转换效率为10.4%.Temperature tuned MgO: LiNbO3 doubly and singly resonant optical parametric oscillators (OPO including DRO and SRO) pumped by the second harmonic of a pulsed Q-switched Nd:YAG laser have been demonstrated. The OPO's tuning ranges at the doubly and singly resonant forms tuned with temperature were 844.l-1411.3nm and 738.9-1032.2nm and the minimum pump thresholds were 0.22mJ/pulse and 0.66mJ/pulse, respectively. The maximum conversion efficiency of energy was 10.4%.
