Description
Technical Field
The invention relates to the technical field of laser, in particular to a high-power cladding light stripper of a fiber laser.
Background
The optical fiber laser has the advantages of good beam quality, good heat dissipation effect and easy realization of high power, and attracts more and more attention. Especially after the double-clad fiber and the cladding pumping technology are widely used, the fiber laser can easily realize the output of tens of thousands of watts. In general, pump light is transmitted in the cladding of an optical fiber, laser light or signal light is transmitted in the core, and at the laser output end, the remaining light is in the cladding. If the residual light is not processed, the quality of the output laser beam is deteriorated, and meanwhile, the coating layer absorbs and generates a large amount of heat to burn the optical fiber, so that the output equipment of the optical fiber laser is damaged. Therefore, necessary measures are taken to filter out the residual light within the cladding. Currently, several forms are commonly used for filtering the cladding light: the cladding structure of the optical fiber is corroded by hydrofluoric acid and the like, the stripping effect and the temperature distribution uniformity can be achieved by the method, but the method is limited in that the mechanical strength of the optical fiber is reduced by corroding the optical fiber; the refractive index matching is coated on the optical fiber cladding, the process is simple, the cost is easy to control, the method has the limitation that the temperature distribution uniformity of the guided-out light has a problem, and the stripping power of the existing refractive index matching glue is maintained at the hundred watt level and is difficult to improve; the soft metal is adopted to absorb the cladding for transmitting light, the stripping effect and the temperature distribution uniformity can be both achieved, but the method has the limitation that the preparation process is complex, and the soft metal is difficult to completely infiltrate into the optical fiber cladding; the glass sleeve and the optical fiber cladding are welded and jointed, so that the stripping effect and the temperature distribution uniformity are ensured, but the method is limited in that the optical fiber cladding and the glass sleeve are difficult to be tightly welded and jointed. Patent CN102255235A discloses leakage by gluing so that the partial mode of the inner cladding does not satisfy the total reflection condition. This approach is limited by the difficulty in stripping low order modes in the cladding, and the difficulty in achieving high power cladding light stripping without subsequent heat treatment. Patent CN102255227A proposes roughening the surface of the inner cladding of single-clad fiber or double-clad fiber to destroy the total reflection condition of the cladding or inner cladding. And the length of optical fiber is cooled with cooling water. The limitation of this approach is that soaking the fiber in water accelerates the aging of the fiber. In addition, the mechanical properties of the optical fiber after roughening become poor, and the optical fiber is easily broken by water impact. Patent CN103269010A proposes a method for filtering out cladding light by coating multiple sections of high refractive index filter materials with different refractive indexes on the inner cladding, which improves the uniformity of the temperature distribution of the outgoing light, but has the limitation that it is difficult to realize the stripping of high power cladding light. In view of the above drawbacks, it is desirable to design a high power cladding stripper for fiber lasers.
