Abstract
We relate on a series of optical nonlinear propagation phenomena, mediated by photorefraction, present in ferroelectric crystals heated above the Curi e point, in proximity of the critical regime. In particular, we discuss cen trosymmetric screening solitons, diffusion-driven anisotropic nonlinear dif fraction, ellipticity locking, diffusion-driven solitons, and spatial beam head-on collisions.
