Abstract

We have recorded running holograms in a photorefractive crystal with an applied electric field, using a 90° phase-shift fringe-locked interference pattern of light. This method provides a simple way to obtain optimal conditions for nonstationary holographic recording. The experiment that we describe allows us to calculate the crystal diffusion length L_D and provides direct evidence of the occurrence of running holograms in photorefractive crystals. Experimental results for a Bi₁₂SiO₂₀ sample are reported.
