Abstract
According to one aspect, the invention relates to a device comprising an optical fiber having a high Brillouin threshold, said device including an optical fiber () suitable for propagating a high-power optical signal beam, means () for coupling a signal beam to an entrance end of the optical fiber () and a tubular structure () comprising at least one first tube () and at least one first adhesive material (). According to the present description, at least one portion of the optical fiber is immobilized in the tubular structure () by means of the first adhesive material (), which adheres both to the internal surface of the first tube () and to the external surface of the optical fiber (). Furthermore, at room temperature and with no other external stresses on the device, the immobilized portion of the optical fiber () is maintained in a compressive state by the tubular structure, the compressive state being such that the relative deformation of the optical fiber is negative or zero in its portion immobilized in the tubular structure, the maximum value of the relative deformation of the immobilized portion of the optical fiber being higher in absolute value than 0.3%.
