Paper Abstract

We demonstrate the storage of 1000 holograms in LiNbO3:Fe, recorded at 488 nm and read at 633 nm to reduce decay during read-out. We minimize Bragg mismatch problems of the two-wavelength scheme by using thin crystals, while combining peristrophic and angle multiplexing to counter the poorer angular selectivity of thin crystals. We find the reduction in read-out decay to be significant, but limited by dark conductivity.
