Abstract:
1. A fiber amplifier system comprising: a master oscillator generating a signal beam; at least one beam splitter splitting the signal beam into a plurality of fiber beams; a plurality of phase modulators each receiving one of the fiber beams, said phase modulators providing phase modulation; a plurality of fiber amplifiers each receiving a fiber beam from one of the phase modulators, said fiber amplifiers amplifying the fiber beams, said fiber amplifiers each including an output end; at least one 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; a plurality of optical output channels each being coupled to a separate one of the output end fibers and providing an output beam; and a phase processor receiving a phase signal from the optical channels and controlling the phase modulators, said phase processor providing phase control so as to direct the combined beam to a selected one of the optical output channels.
