Abstract

We investigate polynomial Gaussian beams with rotationally symmetric Gaussian envelops and complex bivariate polynomial prefactors of finite order. A formalism for the propagation of such beams is developed, which expresses how the coefficients of the polynomial transform during propagation. This formalism is used to proof that global topological charge is conserved for this class of polynomial Gaussian beams.
