Effects of scattering on the dynamics of holographic recording and erasure in photorefractive lithium niobate

Abstract
Absorption and scattering, or fanning, have a pronounced effect on the observed dynamics of the photorefractive effect. In this article these effects are included in the coupled wave equations for both recording and erasure, and a comparison is made with experimental observations. It is shown that a single recording and erasure time constant is necessary to fit the experimental measurements, whereas separate time constants would be required if absorption and scattering were neglected.
