Patent

CA 2196170

A high-power optical fiber device comprising a pump source of light-emitting facets (110), optical means (102) for collimating an d converging the array, an optical beam rotator (130) for transforming the array by rotating individual light emissions, and an optical fiber structure (170) having a core (174) surrounded by an inner cladding (172) for transferring pump energy into the core, the inner cladding having a cross-sectional shape in the form of a convex polygon.

L'invention concerne un dispositif à fibre optique de grande puissance comportant une source de pompage constituée de facettes électroluminescentes (110), un système optique (102) permettant la collimation et la convergence du réseau, un rotateur de faisceau optique (130) permettant de transformer le réseau par rotation des émissions lumineuses individuelles, et une structure à fibre optique (170) possédant une âme (174) entourée par un revêtement intérieur (172) destiné à transférer l'énergie de pompage dans l'âme, ce revêtement intérieur présentant une section de forme polygonale convexe.
