description

National audience; Nous montrons que les impulsions paraboliques ne sont pas systématiquement synonymes de similaritons : un régime d'amplification dominé par l'auto-modulation de phase peut ainsi précéder le régime auto-similaire. Les caractéristiques des impulsions obtenues après recompression sont étudiées. Nous démontrons également qu'une impulsion parabolique de chirp initial négatif subit une recompression spectrale, conduisant à une impulsion parabolique de haute-énergie et en limite de Fourier.
