A new interpretation of two-beam energy coupling in terms of bragg diffraction in a photorefractive crystal

Open Access Open Access

Abstract

Bragg diffraction of a strong reference beam from a steady-state photorefractive grating is measured experimentally and an analytic prediction is derived from the coupled wave equations of two-beam energy coupling. The relation between Bragg diffraction and two-beam coupling is used to check the mechanism of photorefractive grating formation.
