Abstract
A system for combining multiple fiber amplifiers, or multiple fiber amplifiers. The system includes a fiber combiner with multiple cores for connecting with the multiple fiber amplifiers and for combining the beams of the fiber amplifiers into a single beam. The fiber amplifiers are aligned, tapered, and stretched. A method for combining fiber amplifiers includes emitting a beam from a tapered fiber combiner and transmitting and coupling a portion of the emitted beam back into the fiber combiner via a feedback fiber. The transmission and coupling of the feedback fiber includes mixing the feedback fiber with the output of an auxiliary laser and boosting the feedback fiber by a pre-amplifier. The feedback fiber is split into a plurality of beams by a fiber splitter. The beams are fed into an array of fiber amplifiers and combined with output of the individual fiber amplifiers to form the tapered fiber combiner.
