Comparison of different methods for stripping cladding light in the high-power fiber laser

摘要

Different methods for stripping cladding light in the high-power fiber laser have been presented. Original fluoroacrylate jacket of fiber selected 50mm-length is continuous removed, then use three different index polymers recoated the selected section to make the uniform light stripping possible. The power-handling capability of the device is tested over 140W cladding light, attenuation of 15dB is achieved and the local temperature does not exceed 70°C.
