Abstract: A model of coupled modes is proposed, which makes it possible to describe the propagation of a pump wave and a Stokes component in a multimode graded-index fibre. A decrease in the depression in the centre of the profile of the pump wave intensity distribution as a result of the influence of Kerr effects and random linear coupling of modes is demonstrated.

Keywords: multimode optical fibre, nonlinear effects, numerical simulation, stimulated Raman scattering.
