Claim:
1. A fiber-optic device having a high Brillouin threshold comprising: an optical fiber suitable for the propagation of a signal beam of high optical power and having an external surface; means for coupling a signal beam into an entry end of the optical fiber; and a tubular structure comprising at least one first tube with an internal surface and at least one first adhesive material, wherein: at least one portion of the optical fiber is immobilized in the tubular structure by the first adhesive material adhering to the internal surface of the first tube and to the external surface of the optical fiber, and 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, such that the strain of the optical fiber is negative or zero in its portion immobilized in the tubular structure, the maximum absolute value of the strain of the immobilized portion of the optical fiber being greater than 0.3%.
