Abstract

The space domain offers a broad prospect for stationary shock (or kink) wave observation (Wan, 2007), in particular, due to the possibility to control the diffraction properties of beams (i.e., phasing of spatial spectral components) in fabricated or optically-induced periodic lattices (Kartashov, 2006). Photorefractive materials are excellent candidates for experiments with spatial shock waves since they offer tunability of nonlinear response and can be used for lattice induction. Bulk photorefractive crystals with focusing local drift and nonlocal diffusion nonlinearities allow formation of steady-state shock waves, which, however, contain modulationally unstable pedestals.
