MM Combiners
Quick Overview
Our range of multimode pump combiners for pumping high-power fiber lasers is based on the precise fusion of multimode fibers techniques.
For pumping of complex fiber amplifier designs, we have developed a signal feedthrough fiber at the center of the multimode fiber bundle, which is both single-mode and polarization-maintaining.
We manufacture Nx1 multimode combiners as well as N+1×1 combiners with a signal feedthrough fiber. Standard components are 3×1, 7×1, 2+1×1 and 6+1×1. All variants are available with custom pump, signal, and output fibers.
