2μm波段再入射离轴积分腔输出光谱设计与实验
|
摘要
离轴积分腔输出光谱技术(off-axis integrated cavity output spectroscopy, OA-ICOS)是一种高灵敏度的激光光谱测量技术.但由于使用密集的高阶模进行光谱探测,OA-ICOS输出信号强度较低,使得探测灵敏度高度依赖于光源功率.针对该问题,本文引入光学再入射的方法,使激光再次注入光腔,以提高能量利用率和输出信号强度.本文使用三维光追踪模拟软件,设计再入射结构,研究了影响信号增益的多个因素.并搭建一套2μm波段的再入射OA-ICOS装置,开展了一系列研究实验.实验数据表明:再入射方法使OA-ICOS信号增强了8倍,信噪比提升了4.6倍,有效改善了探测灵敏度和光谱的吸收深度,缓解了探测中遇到的信号功率低的问题,为使用低功率光源和高反射率腔镜提供了有效的方法.
Off-axis integrated cavity output spectroscopy(OA-ICOS) is a highly sensitive laser spectroscopy technique. However, due to the use of dense high-order modes for detection, OA-ICOS signal power is low, thus making the detection sensitivity highly dependent on the laser power. To this problem, we introduce an optical re-injection method to re-inject the laser back into the optical cavity again, improving the utilization of laser energy and the power of signal. In this paper, we use optical tracking software to design a re-injection structure,and study several factors affecting the signal gain. Then, we build a re-injection OA-ICOS device in the 2 μm band and also conduct a series of experimental researches. Our results show that the re-injection method enhances the OA-ICOS signal power 8 times and signal-to-noise ratio 4.6 times, which effectively improves the detection sensitivity and the absorption depth of the spectral signal, and alleviates the problem of low signal power in OA-ICOS detection.
