Abstract
Photorefractive holograms stored in Sr(0.75)Ba(0.25)Nb(2)O(6) 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.Entities:
