Title (EN) OPTICAL FIBER AMPLIFIER
(FR) AMPLIFICATEUR DE FIBRE OPTIQUE
Abstract: front page image
(EN)An optical system comprising: a fiber amplifier comprising an optically active doped fiber; a source of seed pulses; and a pump source. The doped fiber is doped with one or more active element(s) selected such that the seed pulses are amplified in intensity. The doped fiber has a negative (anomalous) group velocity dispersion in the region from the wavelength of the seed pulses to a threshold wavelength at which the magnitude of the optical loss of the doped fiber is greater than a gain due to stimulated Raman scattering.
(FR)L'invention concerne un système optique qui comprend : un amplificateur de fibre contenant une fibre dopée optiquement active ; une source d'impulsions initiales ; et une source de pompage. La fibre dopée est dopée avec un ou plusieurs éléments actifs choisis de telle sorte que les impulsions initiales soient amplifiées en intensité. La fibre dopée présente une dispersion négative (anormale) de vitesse de groupe dans la zone allant de la longueur d'onde des impulsions initiales à une longueur d'onde seuil à laquelle l'amplitude de la perte optique de la fibre dopée est supérieure au gain résultant de la diffusion Raman stimulée.
