报道了一种低阈值、窄线宽太赫兹波参量振荡器，它采用腔内掠入射光栅和1 mm厚、45 mm长的锂酸盐平板波导。在主动调Q Nd：YAG激光泵浦下，参量振荡器的阈值能量和强度分别为2.2mJ和70 MW/cm（2）。输出的太赫兹波的线宽为12和134 GHz的腔内光栅和没有，分别。
We report a low-threshold, narrow-line THz-wave parametric oscillator with an intra-cavity grazing-incidence grating and a 1-mm thick, 45-mm long lithium-niobate planar waveguide. When pumped by an actively Q-switched Nd:YAG laser, the threshold energy and intensity of the parametric oscillator were about 2.2 mJ and 70 MW/cm(2), respectively. The linewidths of the output THz wave were 12 and 134 GHz with and without the intra-cavity grating, respectively.
