2014 On étudie à la fois théoriquement et expérimentalement la multistabilité et les instabilités temporelles de processus ondulatoires non linéaires dans les conditions de transfert d'énergie et de compétition entre les différentes composantes de polarisation, pour un milieu anisotrope inhomogène présentant une non-linéarité à seuil. Dans de telles interactions, il se produit un couplage rétroactif lorsque le rayonnement laser induit un réseau d'indice de réfraction dans le milieu, à cause de la réponse non locale du milieu élastique anisotrope au champ extérieur. Abstract. 2014 The multistability and temporal instabilities of nonlinear wave process with an energy transfer and competition between different light polarization components have been studied both theoretically and experimentally for a nonhomogeneous anisotropic medium with threshold nonlinearity. A feedback for such wave interactions, when the laser radiation induces the bulk-gratings of refractive index, arises because of the non-local response of the anisotropic elastic medium on the external field.
