Paper Abstract

A novel design and fabrication method of a (2+1) ×1 taper-fused all-fiber side-pumped combiner is reported. The pump coupling efficiency of this pump combiner was studied theoretically and experimentally. The measurement results indicated that the coupling efficiency of the pump light is 96.5%, the signal-to-pump isolation reaches 31dB, and the signal loss of the combiner is 0.19dB. A backward-pumped fiber laser system was established by using this (2+1) ×1 side-pumped combiner directly, achieving a signal laser output of 1007W with M2=1.33.
