Demonstration of a novel cladding light stripper fabrication method based on poly (Chloro-P-Xylene) polymer material

Abstract

Cladding light stripper (CLS) is a key component for high power fiber laser systems to remove the unwanted light sources out of the system effectively. If they cannot be removed out of the system, the quality of the laser beam is affected severely. For that purpose, the fabrication of CLS has been investigated for years based on two main approaches. One of them is etching method [1] , [2] and the other one is the coating method [3] , [4] . The CLS fabrication based on the recoated polymer has a problem of power scaling whereas the other one is more fragile since the fiber is deformed even though they are more capable of handling power. However, in this work we present a new method to coat a special polymer material on top of the fiber with Chemical Vapor Deposition (CVD) method with a high precision level in the range of nm scale.
