| 摘 要： | 采用电光调Q脉冲Nd:YAG固体激光器的532 nm绿光作为抽运光源(10～13 ns,0～20 mJ),以Ⅱ类相位匹配(θ=57.5°Φ=0°)、尺寸为4 mmX 4 mm×12 mm的三硼酸铋晶体(BiB3O6)与一对1215 nm单谐振波长的平镜组成腔长为40 mm的谐振腔,构建了光参变振荡器的整个实验系统.系统将入射抽运光振荡产生1215 nm的信号光及946 nm的闲频光,结果显示,抽运阈值为9 mJ,最高耦合输出为2.57 mJ,抽运脉冲能量与信号脉冲能量的最高转换效率为14.59%. |

| Abstract: | A nanosecond optical parametric oscillator (OPO) pumped by an electro-optic Q-switched Nd∶YAG laser with 532 nm green light (10～13 ns, 0～20 mJ) was constructed. The resonant cavity of 40 mm long was made from a BiB3O6 crystal of size 4 mm×4 mm×12 mm with type-Ⅱ phase matching (θ=57.5°, Φ=0°), and a pair of plane mirrors with singly-resonant wavelength 1215 nm. The OPO system converted the incident pump beam into the signal laser of 1215 nm and the idler laser of 946 nm. The pump threshold of 9 mJ and the highest coupling output of 2.57 mJ for the highest conversion efficiency of 14.59% were achieved. |
