Abstract

We present an experimental setup for the optical storage of information via refreshing by inverse seeding on the basis of a photorefractive BCT crystal. The setup consists of two four-wave mixing processes with common amplified signal waves and phase-conjugated (pc) waves. This arrangement offers an opportunity to store optical information dynamically for at least 20 min with permanent strength of the hologram.
