Paper Abstract

High power fiber lasers deliver multiple kW laser power with a diffraction limited beam quality. A drawback for some applications is the arbitrary polarization. We report on experimental and theoretical results of kW class cw fiber lasers with linear polarization. A comparison of different concepts for generation of polarized high power output will be presented. The most feasible design for kW class power scaling will be selected. In order to find an empirical formula for calculating bend loss, additional measurements are carried out and are then compared to the theoretical results.
