Abstract
A fiber amplifier system including a plurality of fiber amplifiers each receiving a fiber beam and a tapered fiber bundle (TFB) combiner including a plurality of input end fibers, a plurality of output end fibers and a center bundle portion, where each input end fiber is coupled to a separate one of the fiber amplifiers, and where the bundle portion combines all of the fiber beams into a single combined beam and each output end fiber being capable of receiving the combined beam separately from the other output end fibers. The system also includes a low non-linear delivery fiber coupled to an output end fiber of the TFB combiner and an optical output turret coupled to the delivery fiber opposite to the TFB combiner, wherein the non-linear delivery fiber is configured to reduce the effect of cross-phase modulation (XPM) instability in the delivery fiber.
