摘要：

We derive exact expressions for the evolution of the second order moment of the intensity distribution of an arbitrary beam propagating in a nonlinear Kerr medium with a quadratic index profile. The results can be recast in terms of the ABCD matrix formalism after introducing a generalized complex radius of curvature, Q(z). Various definitions of the beam quality factor are introduced. Numerical simulations reveal the interest of this approach.
