Hologram storage and retrieval in photochromic strontium titanate crystals.
Experimental results are here presented to show that hologram efficiencies of 1.2% can be obtained with photochromic SrTiO(3) materials and that patterns of 10(4) bits/cm(2)can be read out up to 10(7) times before destroying the stored information. It is also shown that the nonlinear absorption properties of the material can be used to store holograms at the ruby laser wavelength where the materials are nominally transparent in the ground state.
