ABSTRACT:
The optical fiber1for an optical fiber laser is provided with a rare earth element doped core2doped with a rare earth element, and a cladding3formed at an outer periphery of the rare earth element doped core2. In the optical fiber1for an optical fiber laser, the rare earth element doped core2is divided into a plurality of core regions2a, 2b, . . . , 2n−1,2nalong a longitudinal direction of the optical fiber1and dopant concentrations of the rare earth element in respective core regions2a,2b, . . . , 2n−1,2nare different from each other, in order to flatten a temperature distribution of the optical fiber1along the longitudinal direction.
