In the present paper we have studied the nonlinear interaction of an electrostatic lower-hybrid wave with a high-power Gaussian EM beam, propagating perpendicular to the static magnetic field in the ordinary mode in a collisionless hot magnetoplasma. On account of the Gaussian intensity distribution of the EM beam in a plane transverse to the direction of propagation, a d.c. component of the ponderomotive force becomes finite and leads to the modification of the background electron/ion density. Thus the electrostatic lower-hybrid wave gets coupled with the pump EM wave. This coupling can lead to the focusing of the lower-hybrid wave and if appropriate conditions are satisfied leads to Brillouin scattering.
