Numerical simulations of two-dimensional beam propagation in polydiacetylene para-toluene sulfonate measured values for [inline formula], predict stable self-trapping and a new phenomenon in which a spatial ring evolves from a Gaussian input beam. We interpret the numerical results theoretically, using the variational model of nonlinear Gaussian beam propagation.
