We demonstrate a monolithic and quasi-phasematched singly resonant cw optical parametric oscillator in periodically poled lithium niobate. The threshold is 1.0 W and the OPO delivers up to 0.98 W signal power tunable between 1750 and 1950 nm (2710 and 2340 nm idler, respectively). We identify cascaded parasitic oscillation effects and analyze their behavior theoretically, showing good agreement with our experiment. The analysis of parasitic effects points the way to improved device designs that should enable stable, compact, and frequency-tunable sources.
我们展示了在周期性极化铌酸锂中单片且准相位匹配的连续波单谐振光参量振荡器。阈值为 1.0 W,光参量振荡器可提供高达 0.98 W 的信号功率,可调谐范围为 1750nm 至 1950nm(相应的闲频光为 2710nm 至 2340nm)。我们确定了级联寄生振荡效应,并从理论上分析了它们的行为,与我们的实验吻合良好。寄生效应的分析为改进器件设计指明了方向,这将使稳定、紧凑、频率可调谐的光源成为可能。
