CA 2470136

A Raman amplifier comprising a microstructured fiber and at least one pump laser, optically connected to one end of the microstructured fiber. The pump laser is adapted for emitting a pump radiation at a wavelength .lambda.p, and the microstructured fiber comprises a silica-based core surrounded by a plurality of capillary voids extending in the axial direction of the fiber. The core of microstructured fiber further comprises at least one dopant added to silica, said dopant being suitable for enhancing Raman effect.

L'invention concerne un amplificateur Raman comprenant une fibre microdimensionnée et au moins un laser à pompe, à connexion optique avec une extrémité de ladite fibre. Le laser à pompe est capable d'émettre un rayonnement pompé, à une longueur d'onde .lambda.¿p?, et la fibre comporte une âme à base de silice entourée de plusieurs vides capillaires qui s'étendent dans la direction axiale de la fibre proprement dite. A la silice de l'âme en question s'ajoute au moins un dopant, lequel est approprié au renforcement de l'effet Raman.
