Abstract
An optimized polymer-based fiber cladding mode stripper (CMS) is presented experimentally. A unique partial fiber stripping method is introduced in CMS fabrication to enable distributed power extraction and temperature along the length of the CMS. The designed CMS based on a 400 µm double-clad fiber (DCF) extracts 300 W of inner cladding power, with an attenuation coefficient of 18.8 dB along with a temperature gradient of 0.17°C/watt. The fabricated CMS is used to develop an all-fiber 150 W thulium fiber laser at 1.94 µm.
