Paper Abstract

We present a theoretical model in which the two-center band-transport equations and the coupled-wave equations are considered simultaneously to study the dynamic holographic storage in photochromic LiNbO3:Fe:Mn crystals. The optimal conditions for processing and material prescriptions are discussed in detail, which include the steady-state recorded space-charge field and the fixed space-charge field, the dopant concentrations of Fe and Mn, the oxidation/reduction degree, the recording sensitivity, the intensities of the coherent writing beams and the UVsensitizing light. The supporting experimental results are outlined, too. Both theoretical and experimental results verify that effectively oxidized processing, high concentration of Fe dopant, moderate concentration of Mn dopant and optimal intensity ratio ofcoherent writing beams to UV-sensitizing light are necessary for nonvolatile holographic storage.
