Abstract

Abstract Plane wave volume holograms have been stored in KCl: Na utilizing the dichroic properties of FA centres. Diffraction efficiences, up to 5·4 per cent, resulting predominantly from phase modulation have been measured for 496·5 nm. The observed results are explained in terms of the dispersion theory, and maximally achievable diffraction efficiencies are predicted for the entire FA absorption range.
