Abstract
A heterodyne phase-controlled beam-combiner system includes a laser source, a first beam splitter, a plurality of phase modulators, a tiled array and an optical mixer. The laser source generates a light beam, and the first beam splitter splits the light beam into multiple beamlets. A phase modulator tags each beamlet with an arbitrary phase dither signal corresponding to an arbitrary phase setpoint or offset, and a tiled array, including a number of lenslets, combines the tagged beamlets and directs the combined light to a second beam splitter. The optical mixer generates a heterodyne light including tagging information. A first output light of the second beam splitter is a target light directed to a target, and the arbitrary phase offset enables achieving a nonflat phase profile for beamlets to obtain the desired on-axis far-field intensity of the target light.
