THE AMPLITUDE AND PHASE OF A TRANSMISSION HOLOGRAPHIC GRATING DUE TO 4-WAVE INTERACTION IN A PHOTOREFRACTIVE MEDIUM

摘要

Based on a previously developed two-level model of four-wave interaction in photorefractive crystals, expressions for the amplitude and phase of a transmission holographic grating have been obtained. The analysis of these expressions points to the dependence of both the amplitude and the phase of the grating on the intensity of the readout beam. References: 11
