摘要：The invention relates a power fiber laser system including at least one single-mode fiber laser, emitting at a signal wavelength, the fiber including at least one outercladding and a core, in which the core of the fiber has a radially graded index. The fiberincludes, at least over a part of its length, a geometrical section having a graded fiber-core radius that decreases between an input end of the section and an output end of thesection, the core radius and the index variation between the cladding and the fiber at theinput end being such that the normalized frequency at the signal wavelength is less thanthe normalized cutoff frequency at which the fiber becomes unimodal.
