Abstract

We create an optical frequency, polarization-independent, narrow bandpass filter of 1.3 GHz (3 dB bandwidth), using the steep dispersion near the rubidium D1 atomic transitions within a prism-shaped vapor cell. This enables us to clean the amplified spontaneous emission from a laser by more than 3 orders of magnitude. Such a filter could find uses in fields such as quantum information processing and Raman spectroscopy.
