我们演示了连续波准相位匹配单谐振光学参量振荡器（SRO）的单频工作。通过采用周期性极化的铌酸锂多光栅芯片，我们获得了从1.66到1.99 mum（信号）和2.29到2.96 mum（惰流）的广泛可调谐输出。使用单频微型Nd:YAG环形激光器作为泵浦源，可以获得具有高光谱纯度和频率稳定性（<10 MHz/min）的SRO输出，可以在2 GHz范围内连续调谐而无模式跳变。通过在SRO腔内对泵浦波进行谐振，获得了最小SRO阈值为260mW。
We demonstrate single-frequency operation of a cw quasi-phase-matched singly resonant optical parametric oscillator (SRO). We obtained widely tunable output from 1.66 to 1.99 mum (signal) and from 2.29 to 2.96 mum (idler) by employing a periodically poled lithium niobate multigrating chip. Using a single-frequency miniature Nd:YAG ring laser as a pump source results in SRO output with high spectral purity and frequency stability(<10 MHz/min), which can be continuously tuned over 2 GHz without mode hops. We obtain a minimum SRO threshold of 260mW by resonating the pump wave in the SRO cavity.
