A beam-superposition technique using diffraction gratings and an aperture-filling technique using an amplitude-to-phase transformation are described. Both these methods are capable of producing a laser beam whose brightness is the sum of the brightnesses of the original lasers (to within 80-95%). Both of these methods are directly applicable to two-dimensional arrays of semiconductor lasers as well as other laser systems.
