The focusing effects of induced phase modulation generated by a strong pump on the propagation of a probe Gaussian pulse in a χ(3) medium are computed. The probe diameter, the radius of curvature, and the phase are expressed as function of the primary pulse (pump) characteristics. It is proved that waveguiding of the probe by the pump is possible.
