Paper Abstract

Holographic characteristic of not-fixed and fixed holographic records in Bi12TiO20 crystal has been investigated. A long-term readout photorefractive memory, implemented in this crystal, has been proposed and demonstrated. The effect is achieved by reading the recorded and fixed hologram with a low-intensity light wave and by additionally amplifying the reconstructed image. Recording and amplification are performed in one and the same crystal. A good quality of the reconstructed image is demonstrated after 60 min of continuous readout of the photorefractive grating.
