description

National audience; Nous présentons ici un dispositif fibré permettant d'exacerber les fluctuations d'intensité d'un train d'impulsions ultracourtes afin de faciliter leur détection. En exploitant l'effet Raman qui induit le décalage fréquentiel de ces impulsions suivi d'un filtrage passe-haut, nous montrons ainsi qu'il est possible de multiplier d'un facteur 13 les fluctuations du train initial.
