Abstract
Photorefractive holograms stored in Sr0.75Ba0.25Nb2O6 crystals are ele ctrically fixed at room temperature. The fixed holograms can be read o ut directly or after a positive-voltage pulse is applied that can dram atically enhance the diffraction efficiency. Single gratings as well a s images are recorded and fixed.
