Abstract

We have demonstrated what we believe to be the first mid-infrared optical parametric oscillator (OPO) pumped directly by a pulsed Tm-doped fiber laser. The Tm-fiber pump laser produces 30 ns pulses with a repetition rate of 30 kHz at a wavelength of 2 microm. The ZnGeP2 (ZGP) OPO produces 20 ns mid-IR pulses in the 3.4-3.9 microm and 4.1-4.7 microm spectral regions simultaneously. More than 658 mW of mid-IR output power has been generated with a total OPO slope efficiency greater than 35%.

摘要

我们展示了我们认为的首个由脉冲掺铥光纤激光器直接泵浦的中红外光学参量振荡器（OPO）。掺铥光纤泵浦激光器产生波长为2微米、重复频率为30千赫、脉宽为30纳秒的脉冲。ZnGeP2（ZGP）光学参量振荡器在3.4 - 3.9微米和4.1 - 4.7微米光谱区域同时产生20纳秒的中红外脉冲。已产生超过658毫瓦的中红外输出功率，光学参量振荡器的总斜率效率大于35%。
