Abstract :
Two non linear mechanisms of amplitude limitation of the supercritical mode of parametric wave phase conjugation are considered for an infinite medium with finite active zone, owing to a 1D numerical simulation. Evolutions of the spatial distribution of the normal stress and temporal form of the conjugate wave are presented for both mechanisms
