Abstract
According to one aspect, the invention relates to an optic fiber amplifier having a high Brillouin threshold, and including: an amplification optic fiber () comprising a core and a sheath and suitable for amplifying a signal beam travelling in said core; means for coupling the signal beam in an input end of said amplification optic fiber; means for coupling a pump laser beam for pumping said amplification optic fiber; a structure () including a deformable portion around which at least one portion of said amplification optic fiber is wound in the shape of turns, said turns being in contact with a surface of said deformable portion, wherein the friction of said optic fiber on said surface resulting, during the deformation of said deformable portion, in an elongation of said amplification optic fiber according to an elongation profile that varies from one turn to the other.
