We report a mid-infrared, CW singly resonant optical parametric oscillator (OPO) with a thermally induced waveguide in its gain crystal. We measured a numerical aperture of 0.0062 for the waveguide at 80-W intracavity power at 3.2 microm. This thermal-guiding effect benefits to the stable operation of an OPO and improves the parametric conversion efficiency by more than a factor of two when compared with that without thermal guiding.
我们报道了一种在增益晶体中具有热诱导波导的中红外连续波单共振光学参量振荡器（OPO）。在3.2微米波长、腔内功率为80瓦时，我们测得该波导的数值孔径为0.0062。这种热导效应有利于OPO的稳定运行，与无热导时相比，参量转换效率提高了两倍多。
