The possibility of focusing a laser beam by the optical inhomogeneities induced by a second strong coaxial laser beam has been investigated. In a particular case in which the power of the strong beam equals the critical power, the medium provides an oscillatory waveguide for the weak beam. When both beams are strong the nonlinearities induced by them are additive, and both beams become focused even when their powers are below the critical powers.
