Abstract
A numerical study of the propagation of intense beams in a quadratic non-li near material is presented, when a second-harmonic amplification process oc curs. Sinusoidal spatial amplitude modulation of the input fields is shown to be able to control the splitting of the propagating beams and their stab ility. We demonstrate that a spatial central of the fields can be performed under appropriate conditions on the amplitude of the interacting fields.
