我们展示了一种太赫兹波参数振荡器（TPO），该振荡器具有由角立方棱镜（CCP）和平面镜组成的角立方谐振腔。通过使用本文中提出的腔结构，可以通过旋转平镜而不是相对于泵浦光束旋转TPO腔来产生可调谐的单色太赫兹（THz）波。通过绕腔轴旋转CCP，可以周期性地控制太赫兹波输出强度和脉宽。与传统的平面-平行谐振腔结构相比，TPO对腔位失调的稳定性显著提高了至少1到2个数量级。
We demonstrate a terahertz-wave parametric oscillator (TPO) with a corner-cube resonator consisting of a corner-cube prism (CCP) and a flat mirror. By using the cavity configuration proposed in this Letter, the generation of tunable monochromatic terahertz (THz) waves can be achieved just by rotating the flat mirror instead of rotating the TPO cavity relative to the pump beam. The THz-wave output intensity and pulse width can be controlled periodically by rotating the CCP around the cavity axis. The TPO stability against cavity misalignment is significantly improved by at least 1 to 2 orders of magnitude compared with the conventional plane-parallel resonator configuration.
