Abstract We have investigated a cesium Faraday filter at 852nm in relatively weak and strong magnetic field, theoretically and experimentally. With a cesium cell of 0.02m length in an axial magnetic field of 0.06T, the line-center operation has been achieved. The calculated peak transmission reached 99% with a full width at half maximum (FWHM) bandwidth of only 3.9 GHz, the measured FWHM bandwidth of the filter is 3.29 GHz, which is in general agreement with the theoretical result.
