| 摘 要： | 研究了掺镁周期性极化铌酸锂光参变振荡器(PPMgLN-OPO)在近红外波段的调谐特性和输出特性。计算了PPMgLN-OPO的调谐曲线,并采用Nd:YVO4激光器产生的1.064μm激光作为抽运源,验证了其温度调谐特性,实现了1.8～2.6μm的可调谐红外激光输出。此外,比较了长度为2cm和3cm的PPMgLN晶体的OPO输出特性,并在抽运功率为6.7W时,获得了最高功率为3.2W的2μm激光输出,转换效率达47.8%。

| Abstract: | Theoretical and experimental study is presented on near infrared band tuning and output characteristics of optical parametric oscillator based on periodically poled MgO:LiNbO3(PPMgLN-OPO).The temperature tuning curve of PPMgLN is calculated.Through OPO experiments based on PPMgLN pumped by a 1.064 μm Nd:YVO4 laser,we realize tunable infrared laser output of 1.8~2.6 μm.We also compare the output characteristics of length of 2 cm and 3 cm PPMgLN crystals.When the pump power is 6.7 W,up to 3.2 W laser output in the 2 μm band is generated with a conversion efficiency of 47.8%. |
