Abstract

We theoretically considered the possibility to exploit nonlinear Fabry–Pérot interferometers to differential gain of terahertz radiation in the field of a pump wave of the same frequency. It is shown that in a mirrorless nonlinear Fabry–Pérot interferometer, that consists of a crystalline quartz plate and which reflection is determined by Fresnel reflectivity only, the regime of maximal differential gain of radiation with central frequency at 1 THz can be observed at the plate thickness of near 1 mm and radiation intensity of 10⁸ W cm^–2 order.

晶体石英中太赫兹辐射在泵浦波场中的差分增益

我们从理论上考虑了利用非线性法布里-普氏干涉仪在相同频率的泵浦波场中对太赫兹辐射的差分增益的可能性。结果表明，在由晶体石英板组成的非线性法布里-帕氏干涉仪中，反射仅由菲涅耳反射率决定，在1太赫兹中心频率下，在板厚接近1 mm，辐射强度为108 W cm-2阶时，可以观察到辐射的最大微分增益。
