| 摘 要： | 报道了一个低阈值宽调谐、被动调Q、单谐振掺MgO的周期性极化铌酸锂晶体（PPMgLN）光学参量振荡器。利用被动调Q的Nd:YVO4激光器作为泵浦源，采用外腔结构，在室温下，实现了PPMgLN晶体的准相位匹配光学参量振荡。光参量振荡的阈值仅为0.27 W（单脉冲能量4.5 μJ、脉宽35 ns）；在泵浦光为1（脉冲能量8.2 μJ、脉宽35 ns），PPMgLN周期为31 μm时，获得了161.9 mW,3.202 μm脉冲激光输出；同时获得了98.5 mW的1.594 μm信号光输出，总的光-光转化效率达到19.3%。通过改变晶体的周期，实现了闲频光3.13~4.19 μm，信号光1.43~1.65 μm的宽带可调谐激光输出。

| Abstract: | A wide-tunable, low-threshold, extra-cavity singly resonant optical parametric oscillator(OPO) has been reported, which is based on periodically poled MgO:LiNbO3 (PPMgLN). The OPO system, compact and simple, adopts a passively Q-switched Nd:YVO4 laser as the pump source and realizes quasi-phase-matched optical parametric oscillation at room temperature. The threshold value of the OPO system is only 0.27 W (single pulse energy of 4.5 μJ, pulse duration of 35 ns) at 1 064 nm. When the pump power is 1.35 W (pulse energy of 8.2 μJ, pulse duration of 35 ns), an idler output power of 161.9 mW at 3.202 μm, and a signal output power of 98.5 mW at 1.594 μm have been achieved, and this corresponds to a whole (idler+signal) optic-optic conversion efficiency of 19.3%.
