Abstract

We demonstrate an isotope Rb Faraday anomalous dispersion optical filter (FADOF) with a single transmission peak resonant with the 5S, F = 2 → 5P, F' = 1, 2, 3 transitions at 780 nm with an enriched Rb isotope at low temperature. The isotope Rb FADOF achieves a single peak transmission of 74.8% with a bandwidth of 0.96 GHz. Compared with most of FADOFs operated at frequencies far from absorption, the isotope Rb FADOF that we have achieved can provide a transmission band exactly covering atomic transitions for many practical applications.

摘要

我们展示了一种同位素铷法拉第反常色散光学滤波器（FADOF），它在低温下使用富集的铷同位素，具有与780纳米处5S，F = 2 → 5P，F' = 1、2、3跃迁共振的单个透射峰。该同位素铷FADOF实现了74.8%的单峰透射率，带宽为0.96吉赫兹。与大多数在远离吸收频率下工作的FADOF相比，我们所实现的同位素铷FADOF能够提供一个精确覆盖原子跃迁的透射带，适用于许多实际应用。
