摘要

最近在太赫兹量子级联激光器(QCL)中展示的自混合效应为该电磁频谱范围内的无探测器传感开辟了新的可能性。在本文中，我们比较了从QCL端子电压变化获得的自混合信号与使用辐射计监测的QCL辐射功率变化获得的信号。我们表明，这两个信号是等效的，允许处置传统的笨重和缓慢的热探测器。

Self-mixing signals in terahertz lasers

Recently demonstrated self-mixing effect in terahertz quantum cascade lasers (QCL) opens new possibilities for detectorless sensing in this range of electromagnetic spectrum. In this paper we compare self-mixing signals obtained from variations in QCL terminal voltage against the signals obtained from variations in QCL radiated power monitored using a bolometer. We show that these two signals are equivalent allowing for the disposal of a conventional bulky and slow thermal detector.
