Digital holograms have been written in stoichiometric Pr:LiNbO3 in a two-color recording scheme, demonstrating what is to our knowledge the first all-optical nondestructive readout of digital data. Using writing light at 800nm and gating light at 476nm, we stored and retrieved 256-kbit digital data pages with a raw bit-error rate BER of <10-4 .
