Patent ID: 8830566

Claim:
A fiber amplifier system comprising: a plurality of master oscillators each generating a signal beam at a different wavelength; a plurality of beam splitters each receiving one of the signal beams and splitting the signal beam into a plurality of fiber beams; a plurality of fiber amplifiers where a separate fiber amplifier is provided for each fiber beam, each fiber amplifier amplifying the fiber beam; a plurality of tapered fiber bundles where a separate tapered fiber bundle is provided for each master oscillator wavelength, each tapered fiber bundle including a plurality of input end fibers, a plurality of output end fibers and a center bundle portion, each input end fiber being coupled to a separate one of the fiber amplifiers, said bundle portion combining all of the fiber beams received by the input end fibers into a single combined beam and each output end fiber being capable of receiving the combined beam separately from the other output end fibers; and a plurality of optical output channels each being coupled to a separate one of the output end fibers from each of the taper fiber bundles.
