Abstract

In this paper we investigated potassium Faraday filter at 770 nm theoretically and experimentally. With a potassium cell of 0.01 m in length in an axial magnetic field of 0.0815T, line-center operation has been achieved. The calculated peak transmission has reached 93% with a FWHM bandwidth of only 1.6 GHz, the measured FWHM bandwidth of the filter is 2.2 GHz, which is in detail agreement with the theoretical result.
