Description
We present the manufacturing of side-fused signal-pump combiners with 25/400-µm signal feed-through fibers and >90% pump coupling efficiency. On the basis of CO2-laser restructuring of the used optical fibers, the necessity of splice connection is avoided, which improves the pump coupling efficiency and thus overall laser efficiency.
