Abstract
Another optical nonlinear effect is reported: the transient self-bendi ng of a laser beam within a photorefractive crystal under an external electric field. It is based on the large drift length of the photoindu ced carriers and is observed during a transient regime immediately aft er applying the light beam. Results of a numerical simulation are supp orted by an experimental demonstration of the effect in cubic Bi12TiO2 0 at lambda=633 nm.
