HIGH-POWER OPTICAL FIBER AMPLIFIER OR LASER DEVICE

摘要

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.
