Abstract:
1. A method of combining beams from a plurality of laser emitters into a single mode, single frequency, coherent output beam, the method comprising: arranging a plurality of laser emitters along at least one plane and facing in one direction in an arrangement having first and second lateral ends; injecting an initial laser beam into one of the plurality of laser emitters to begin a sequence of generating and reflecting a laser beam between laser emitters, such that the laser beam travels to others in the plurality of the laser emitters; reflecting at least a portion of a laser beam from each of the laser emitters back to another one of the laser emitters to cause a beam to be generated from the other one of the laser emitters; transmitting another portion of the laser beam from each of the laser emitters to produce a laser output beam; wherein a plurality of laser output beams having a single laser mode are generated from the respective laser emitters; and combining the plurality of laser output beams into a single mode, single frequency, coherent output beam.
