Numerical and analytical solutions of the evolving beam shape, beam curvature and optical phase shift are obtained from a variational analysis of the paraxial wave equation, describing nonlinear optical beam propagation in thick media. Arbitrary pre-focusing is included in the description. The prope
## Abstract Secondβorder nonlinearity in optical media acts as a source for harmonics generation. We set up a timeβdomain model that accounts not only for the second harmonic, but also for the higher harmonics that are induced by a beam propagation. The model is solved numerically using a secondβor
