We consider the nonlinear dynamics occurring when an optical beam couples to dielectric material polarization in an unbiased photorefractive crystal undergoing a ferroelectric phase transition. The polarization profile produced by the light-induced electric field is evaluated by means of the Landau–Ginzburg approach and is found to manifest new thermodynamical states with their own specific nonlinear optical effects. We show that a temperature T C , lower than the critical one, exists such that (a) if T > T C the optical beam experiences an increasing self-focusing for decreasing temperatures and (b) if T < T C the optical beam allows the existence of thermodynamically metastable states associated with an optical ultra-self-focusing effect.
