Abstract
We describe a technique for investigation of beam coupling in photorefractive materials. We used a probe beam which partly erases the recorded hologram in a small region of the crystal. This erasure changes the coupling between the beams, then the output intensities of these beams are changed. We show by numerical simulations that these changes give us information about coupling coefficient along the length of the photorefractive sample. We compare the numerical results with experimental data of two-beam coupling in an optical active BTO waveguide-like crystal.
