In the present paper we investigate the possibility of controlling the nonlinear dynamics induced by the occurrence of molecular reorientation in a liquid crystal which interacts with a linearly polarized optical field at a small angle of incidence. The control is achieved through the addition of a counter-propagating orthogonally polarized beam. This beam, propagating inside the medium, changes the dynamics of the system, thus allowing us to observe a sequence of different scenarios.
