description

National audience; Nous démontrons l'amplification d'impulsions pico- et femto-secondes par un dispositif fibré à un taux de répétition de 1 GHz obtenu par utilisation d'un VECSEL passivement mode-locké. Deux régimes non-linéaires d'amplification sont alors clairement mis en évidence, l'un dominé par l'auto-modulation de phase et l'autre par une évolution autosimilaire. Ce dernier régime conduit après recompression temporelle à des impulsions en limite de Fourier avec une durée temporelle inférieure à 150 fs.
