我们报道了一种宽调谐连续波单频泵浦谐振信号谐振光学参量振荡器(PRSRO),在中红外(1.7 μm和3.5 μm)范围内提供20 mW至50 mW的闲频功率,跨越倍频程带宽。PRSRO由Ti:Al2O3环形激光器泵浦,在λp=795 nm附近输出760 mW,并且由于泵浦增强,使用多光栅温度调谐MgO掺杂的双极化LiNbO3实现了低至110 mW的阈值。该PRSRO将用于基于腔衰荡光谱的多组分痕量气体传感。
We report on a widely tunable continuous-wave single-frequency pump-resonant signal-resonant optical parametric oscillator (PRSRO) delivering 20 mW to 50 mW of idler power spanning an octave bandwidth in the mid-infrared (1.7 µm and 3.5 µm). The PRSRO is pumped by a Ti:Al2O3ring laser delivering 760 mW aroundλp=795 nm, and thanks to the pump enhancement a threshold as low as 110 mW is achieved with a multi-grating temperature-tuned MgO-doped periodically-poled LiNbO3. This PRSRO will be used for multi-species trace gas sensing based on cavity ring-down spectroscopy.
