Abstract

We present the first to our knowledge continuous-wave singly-resonant optical parametric oscillator (SROPO) generating tunable signal and idler waves with less than 100 mW single-frequency pump power. This low threshold is achieved by an additional intracavity gain medium that is pumped incoherently. The idler power with respect to the single-frequency pump power shows a bistable behavior which depends strongly on the pumping of the additional amplifier. Furthermore, we demonstrate that such a setup allows a SROPO to be completely diode pumped.

摘要

据我们所知，我们首次展示了一种连续波光单共振光学参量振荡器（SROPO），它能够在单频泵浦功率低于100 mW的情况下产生可调谐的信号波和闲频波。这种低阈值是通过一个额外的非相干泵浦的腔内增益介质实现的。闲频功率相对于单频泵浦功率呈现出双稳态行为，这在很大程度上取决于额外放大器的泵浦情况。此外，我们证明了这样一种设置允许SROPO完全由二极管泵浦。
