Abstract
We have demonstrated that holographic storage by optical damage in BaTiO3 crystals is enhanced by doping with Fe3+ and Ni2+, while doping by Nb5+ produces the inverse effect. Stable holograms have been obtained, by applying a pulsed electric field of amplitude slighty smaller than the coercitive field. Erasure is achieved by applying a saturation field.
