  • Phase and polarization controlled beam combining devices and methods
    Patent number: 7817688
    Abstract: A controller, such as a programmable logic controller, may manipulate a phase and/or polarization module to alter and/or control the phase and polarization of input beams. Utilizing active phase and polarization control can enable the combination of any arbitrary number of input beams into a single, combined beam. Utilizing active phase and polarization control can also enable the combination of input beams having arbitrary power levels.
    Type: Grant
