The imaging properties of Gaussian beams of light passing through a nonlinear graded-index rod are studied for the first time to our knowledge. The beam-width parameter, the distance of the focal plane, and the linear magnification in terms of the beam power, diffraction, and the rod dimensions are derived by using the variational approach and the ABCD law of Gaussian beam propagation. A comparison of these results with those derived from the ray equation and the linear case shows that the effects of the beam power on the imaging characteristics are significant.
