Abstract

Photorefractive holograms stored in Sr_0.75Ba_0.25Nb₂O₆ crystals are electrically fixed at room temperature. The fixed holograms can be read out directly or after a positive-voltage pulse is applied that can dramatically enhance the diffraction efficiency. Single gratings as well as images are recorded and fixed.
