Abstract. The light beam behaviour in nonlinear media is considered in the case when the nonlinear polarization contains susceptibilities of third and fifth order. Taking in to account that the last ones can take different signs a number of new solitary solutions for the nonlinear differential equations deduced are found in analytical form. The effects of self-action (self-channelling)are considered. Numerical values and estimations are presented.
