Abstract: Systems and methods for forming a coherent optical phased array laser source from a spatially combined array of output beams is accomplished without any external measurement devices or wavefront sensors. A master oscillator laser is split into a plurality of optical beam transport and amplifier channels to produce a plurality of optical output beams that are spatially combined in an array format. The spatial phase state of the plurality of output beams is measured at the output of a spatial combiner without use of an external measurement device or sensor. The phase of the plurality of optical output beams is controlled to compensate both for aberrations induced by the optical beam transport and amplifier paths to produce a coherent and spatially phased laser beam at the output of the laser source or to produce a phased laser beam with prescribed phase state on each output beam.
