Abstract
We have observed efficient two-photon, two-step recording in a praseod ymium-doped lithium niobate crystal by use of cw lasers. Single-photon erasure during the readout at near-infrared wavelengths was found to be negligible. Nonvolatile holographic image storage was demonstrated. This progress is an important step in the realization of an economica lly feasible nonvolatile read-write holographic recording system based on low-cost semiconductor diode lasers.
