Abstract. The light beam behaviour in nonlinear media is considered in the case when the nonlinear polarization contains susceptibilities of third and fifth order. A number of soliton solutions of the nonlinear differential equations describing self-action effects is obtained in analytical form. The existence of the solitary pulses obtained is discussed from energetically point of view.
