Abstract

By combining the band-transport equations with the coupled wave equations, we obtain a self-consistent set of equations governing the recording of photorefractive holograms. Using the results of this model leads to accurate predictions for the observed intensity coupling and holographic diffraction efficiency. The model also predicts complicated dynamics for long recording times. The origin of this prediction is discussed and is found to be due to a new effect, which is called transient fringe dislocation.
