We report an excited-state Faraday anomalous-dispersion optical filter operating on the rubidium 5P(3/2)-5D(5/2) transition (775.9 nm in vacuum) without the use of a pump laser. An electrodeless discharge vapor lamp is employed to replace the Rb vapor cell in a traditional Faraday anomalous-dispersion optical filter system. Atoms can be excited by power rather than a complex frequency-locked pump laser. A proof-of-concept experimental demonstration with a maximum transmission of 1.9% and a filter bandwidth of 650 MHz is presented.
我们报告了一种基于铷 5P(3/2)-5D(5/2)跃迁（真空中的 775.9nm）的激发态法拉第反常色散光滤波器，无需使用泵浦激光。我们使用无电极放电蒸气灯代替传统的法拉第反常色散光滤波器系统中的铷蒸气池。原子可以通过功率而不是复杂的频率锁定泵浦激光来激发。我们进行了一个概念验证实验演示，最大透过率为 1.9%，滤波器带宽为 650MHz。
