Patent 7848370 was granted and assigned to Telaris, Inc. on December, 2010 by the United States Patent and Trademark Office.
Semiconductor diode lasers are phase-locked by direct current injection and combined to form a single coherent output beam. The optical power is amplified by use of fiber amplifiers. Electronically control of the optical phases of each emitter enables power efficient combining of output beams to be maintained under dynamic conditions.
