description

International audience; We describe the influence of the initial phase profile on the convergence towards asymptotic self-similar parabolic shape. More precisely, based on numerical simulations, we discuss the impact of an initial linear chirp and a p phase shift. If the parabolic shape has been found to describe accurately the pulse envelope, dark structures can appear and evolve also self-similarly on the parabolic background.
