本文报道了一种无需抽运激光，工作在铷原子5 P（3/2）-5D（5/2）跃迁（775.9nm）的激发态法拉第色散滤光器。采用无电极放电蒸气灯代替传统的法拉第色散滤光系统中的铷蒸气室。原子可以由功率而不是复杂的锁频泵浦激光激发。最大传输率为1.9%，滤波器带宽为650 MHz的概念验证实验演示。
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.
