The complex ray representation of Gaussian beams proposed by the author in 1968 is applied to the propagation of pulses with Gaussian envelope. Linear propagation in uniform time-invariant waveguides is first considered. Next, closed-form solition solutions are obtained for a special kind of nonlinearity.
