摘要

顺磁气体的多通细胞增强法拉第旋转光谱受细胞镜内相互作用引入的椭圆偏振的影响。我们演示了使用四分之一波片减少不必要的椭圆率，并量化了信噪比的改善。

Optimization of the output polarization state in multi-pass cell enhanced Faraday rotation spectrometers

Multi-pass cell-enhanced Faraday rotation spectroscopy for paramagnetic gas species is affected by elliptical polarization introduced by interactions within the cell mirrors. We demonstrate a reduction in unwanted ellipticity using a quarter wave plate and quantify the improvement in SNR.
