Abstract:
The Faraday rotation associated with the Zeeman effect in gases is used to rotate the plane or polarization of plane polarized light with low loss of intensity. Advantage is taken of the rapid decrease of absorption relative to Faraday rotation between the split Zeeman components. Calculations of this Faraday rotation are applied to obtain design parameters for an isolator for 5.26 μm which show a significant improvement over conventional designs.
