Abstract

The invention relates to a temperature controlling device for increasing a fiber SBS (Stimulated Brillouin Scattering) threshold, belonging to the field of high-power narrow-linewidth fiber lasers and narrow-linewidth fiber amplifiers. The invention solves a technical problem that the current device has the disadvantages of complex process, no recoverability of optical fibers, small shrinkage of the optical fibers and the like. In the temperature controlling device, a first regulating screw (51) and a second regulating screw (52) are respectively connected with one ends of a first extension spring (61) and a second extension spring (62); the other ends of the first extension spring (61) and the second extension spring (62) are respectively connected with an inner sidewall and an outer sidewall of a thin tube (4); a temperature controller load (32) is arranged in a heat insulating box (1) and is connected with a temperature controller (31); and a rare-earth doped fiber (7) penetrates into the heat insulating box (1) through a first small through hole (21) arranged in a heat insulating cover (2), is spirally adhered on the outer sidewall of the thin tube (4)and then penetrates out through a second small through hole (22) arranged in the heat insulating cover (2).

Description

technical field [0001] The invention relates to a temperature control device for increasing the threshold value of optical fiber stimulated Brillouin scattering, belonging to the fields of high-power narrow-linewidth fiber lasers and narrow-linewidth fiber amplifiers. Background technique [0002] Stimulated Brillouin scattering is a nonlinear process that occurs in an optical fiber, and its required incident power is much lower than that required by stimulated Raman scattering. Once the Brillouin scattering threshold is reached, stimulated Brillouin scattering will convert the vast majority of the input power into reverse Stokes waves [Govind P. Agrawal, Nonlinear Fiber Optics, Third Edition, San Diego, CA: Academic]. Clearly, stimulated Brillouin scattering limits the maximum power that can be transmitted by an optical fiber. In addition, if the stimulated Brillouin scattering cannot be completely suppressed, it will lead to random changes in the pump power, which will ca...
