Paper Abstract

We present a new experimental setup for optical storage of information via refreshing by inverse seeding (OSIRIS), which allows a sixfold increase of the storage time of holograms in a Ba0.77Ca0.23TiO3 crystal. The setup consists of two four-wave mixing processes with common amplified signal waves and phase-conjugated waves. Temporal behaviors of the amplified and pc-signal waves for the OSIRIS experiment as well as for the common four-wave mixing experiment are compared and discussed. The solutions of coupled equations under the depleted-pump approximation are obtained in order to estimate the pc-reflectivities and coupling gains of gratings inside the crystal.
