  • System and method for coherent beam combination
    Patent number: 7884997
    Abstract: Systems and methods for coherent beam combination of lasers are provided. In one embodiment, a method for coherent beam combination is provided. The method comprises providing a plurality of secondary laser signals from a primary laser signal, amplifying the plurality of secondary signals along respective amplifier arms to provide a plurality of amplified output signals, providing a frequency-shifted reference beam from the primary laser signal, generating a plurality of optically heterodyne detected (OHD) beat signals based on combining respective amplified output signals of the plurality of amplified output signals with the frequency-shifted reference beam, and adjusting path lengths of respective amplifier arms based on respective amplitudes of the plurality of OHD beat signals to control the path length of respective amplifier arms to within a coherence length of the primary laser signal.
