Abstract
By direct interferometric measurement in Bi12TiO20 under external DC e lectric field, we demonstrate that the steady-state photorefractive le ns produced by the laser beam with the initial circular cross-section is essentially anisotropic: its focusing strength along the direction of the applied electric field is remarkably higher. Experimental data are supported by computer simulations and analytical results.
