Abstract

An efficient beam-combining technique based on aperture filling is introduced to direct virtually all the energy of a mutually coherent laser array to the far-field main lobe. A comparison between this method and the Dammann grating method for beam superposition reveals the connection between the two and suggests specific applications for each.
