Ultra-Narrow Faraday Rotation Filter at the Rb D1 Line

Abstract

We present a theoretical and experimental study of the ultra-narrow bandwidth Faraday anomalous dispersion optical filter (FADOF) operating at the rubidium D1 line (795 nm). This atomic line gives better performance than other lines for the main FADOF figures of merit, e.g. simultaneously 71% transmission, 445 MHz bandwidth and 1.2 GHz equivalent noise bandwidth.

3 pages, 2 figures. Manuscript same as v1. FADOF calculator (ancillary file) now allows for extension to the D2 line
