Abstract

An oscillatory characteristic of diffraction is observed as a result of strong beam coupling in a weakly oxidized ${\mathrm{LiNbO}}_3:\mathrm{Ce}:\mathrm{Cu}$ crystal during the recording step in the production of nonvolatile photorefractive holograms. On this basis the optimal switching time from the recording step to the fixing step for high diffraction of a fixed hologram is studied. It is shown that switching after the first diffraction maximum leads theoretically to fixed diffraction of as much as 100% with a suitable switching time. Both an experimental demonstration and a theoretical simulation are presented.
