1. A system for producing mutually-coherent operation of a plurality of light emitters, each of the emitters outputting a respective power and brightness, the system comprising:

  • an optical system that mixes respective beams received from each of the plurality of emitters; and

    a beam-combining element that forms at least one composite beam containing a respective contribution from each of the emitters, whereinthe composite beam containing a respective contribution from each of the emitters is fed back in such a way that mutually coherent operation of the plurality of emitters is achieved such that the emitters lase with a phase difference that results in a coherent output beam from the system that effectively combines the powers from each of the emitters.
