Abstract

Experimental results are here presented to show that hologram efficiencies of 1.2% can be obtained with photochromic SrTiO₃ materials and that patterns of 10⁴ bits/cm² can be read out up to 10⁷ 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.
