Abstract
We report experimental results that demonstrate for the first time, to our knowledge, more than 20 holograms stored and recalled with equal diffraction efficiency in photorefractive LiNbO3. A physical explanation for this new recording procedure is presented, and a comparison is made with previous exposure methods that shows an order-of-magnitude increase in diffraction efficiency with the order of exposure for optically erasable holograms. The procedure holds for recording times much less than the saturation exposure time.
