Abstract

In an intermediate asymptotic propagation distance, pulse's self similar evolution is influenced by the initial pulse width and chirp, as a result pulses can not completely evolve into a parabolic pulse, which can affect the compression of the evolved pulse. The self similar evolution results of ultra-short pulse with different width and initial chirp coefficient are studied by numerical simulation. The study shows the wider the pulse is, the worse the self similar evolution and compression are; it also shows the initial chirp can greatly hold out the self similar evolution and compression, the larger the chirp and the wider the pulse, the worse the self similar evolution, and the influence of the positive chirp on the evolution is bigger than that of negative chirp.
