论文摘要
单细胞磁光 - 光学的法拉第滤波器找到了很棒的实用程序，并通过“机翼”或“线中心”光谱轮廓实现。我们表明，具有独立轴向（法拉第）或横向（VOIGT）磁场的第二个细胞在功绩（FOM）和光谱曲线方面的性能提高。第一个单元在光学上旋转光的偏振平面，从而形成了高传输窗口。第二个电池选择性地吸收了消除不需要的传播的光。使用自然丰富的RB蒸气单元，我们实现了Faraday-Faraday Wing滤波器和第一个记录的Faraday-Voigt线中心滤波器，该滤波器与理论表现出了极好的一致性。这两个过滤器的FOM值分别为0.86和1.63 GHz $^{ - 1} $，后者是记录的最大FOM原子线滤波器。
Single-cell magneto-optical Faraday filters find great utility and are realized with either 'wing' or 'line center' spectral profiles. We show that cascading a second cell with independent axial (Faraday) or transverse (Voigt) magnetic field leads to improved performance in terms of figure of merit (FOM) and spectral profile. The first cell optically rotates the plane of polarization of light creating the high transmission window; the second cell selectively absorbs the light eliminating unwanted transmission. Using naturally-abundant Rb vapor cells, we realize a Faraday-Faraday wing filter and the first recorded Faraday-Voigt line center filter which show excellent agreement with theory. The two filters have FOM values of 0.86 and 1.63 GHz$^{-1}$ respectively, the latter of which is the largest FOM atomic line filter recorded.
