| 摘 要： | 报道了一台稳定的、高平均功率连续波光学参量振荡器,该振荡器为单谐振环形腔结构,参量晶体为角度切割的掺氧化镁周期性极化铌酸锂(MgO:PPLN),由一台波长为1064 nm的Nd:YVO4固态激光器泵浦。在9.8 W的泵浦功率下,可得到波长3069.1 nm的闲频光功率2.15 W,其泵浦-闲频光转换效率达21.0%。得益于腔内寄生振荡的减弱以及热自稳效应,振荡器的输出功率在30分钟内的稳定性优于0.19%均方根偏差(rms)。

| Abstract: | We report a stable, high-power, continuous-wave (cw) optical parametric oscillator (OPO) pumped at 1064nm by a commercial Nd:YVO4 solid-state laser. The oscillator is singly resonant, based on an angle-polished MgO-doped periodically poled LiNbO3 (MgO:PPLN) in a four-mirror ring cavity. Maximum output idler up to 2.15 W is achieved at 3069.1 nm for 9.8 W of pump power, corresponding to a pump-to-idler conversion efficiency of 21.9%. The device exhibits an excellent power stability better than 0.19% rms over 30 minutes, which is related to the reduced intracavity residual reflections and thermal self-locking effect. |
