ABSTRACT:
An optical fiber structure for use in gain applications which comprises a core, selectively doped with an active gain species, and an inner cladding surrounding the core, where the inner cladding serves the purpose of receiving multimode pump energy from an external power source, confining this energy, and transferring the energy into the core by means of repeated interactions between the energy and the active dopant within the core as the pump energy propagates along the length of the fiber structure. The cross-sectional shape of the inner cladding is in the form of a non-rectangular, convex polygon so that the propagating pump energy is induced to form an essentially uniform radiation field in which the various radiation modes comprising the pump energy are isotropically distributed.
