Experimental investigation of high power photonic crystal fiber laser

Abstract

Abstract

A high-power Yb3+-doped photonic crystal fiber(PCF) laser based on Fabry-Perot cavity structure was studied. The laser was two-end pumped by two pumping sources at 915 nm and 976 nm, respectively, and a single-mode continuous-wave laser of 552 W was obtained. The laser had a slope efficiency of 76% and an optical-to-optical conversion efficiency of 56%. The central wavelength of the laser was 1 078 nm and the beam quality factor was 1.2.
