I wanted to use a laser with third order dispersion, which should and does produce an asymmetric laser in the longitudinal direction. But using the DispersivePulse incidentField profile the maximum of the pulse is set to be in the centre of the initialisation time. Due to the asymmetry of the laser and the periodicity of the FT used to calculate the laser profile, an edge is formed in the envelope. In the attached picture you can see what I mean.
As an example a simulation with:
