Abstract

We measured cesium magneto-optic line filter spectra at 455 nm for several field orientations. When optimized to achieve the narrowest passbands and the highest transmission, the Faraday filter (B along k) exhibited near-unity transmission peaks of 0.7-GHz bandwidth with an integrated transmission of ∼3 GHz. A transmission calculation that includes the field angle was confirmed experimentally and used to show that the Faraday filter field of view is >60°. We devised a new type of magneto-optic atomic line filter that uses a transverse magnetic field, which we call the Voigt filter.
