We demonstrate a simple scheme to generate 0.4 mJ 11.5 fs laser pulses at 1.8 \u3bcm. Optical parametrically amplified pulses are spectrally broadened by nonlinear propagation in an argon-filled hollow-core fiber and subsequently compressed to 1.9 optical cycles by linear propagation through bulk material in the anomalous dispersion regime. This pulse compression scheme is confirmed through numerical simulations.Nous faisons la d\ue9monstration d\u2019une technique simple pour g\ue9n\ue9rer des impulsions laser de 0,4 mJ \ue0 11,5 fs pour une longueur de 1,8\u2002\u3bcm. Le spectre d\u2019impulsions amplifi\ue9es de fa\ue7on param\ue9trique est \ue9largi par propagation non lin\ue9aire dans une fibre creuse remplie d\u2019argon, puis compress\ue9 \ue0 1,9 cycle optique par propagation lin\ue9aire dans un mat\ue9riau en vrac en r\ue9gime de dispersion anormale. Cette technique de compression d\u2019impulsions est valid\ue9e au moyen de simulations num\ue9riques.Peer reviewed: YesNRC publication: Ye
