title: Generation of higher order Gauss-Laguerre modes in single-pass 2nd harmonic generation.
abstract: We present a realistic method for dynamic simulation of the development of higher order modes in second harmonic generation. The deformation of the wave fronts due to the nonlinear interaction is expressed by expansion in higher order Gauss-Laguerre modes.
