Abstract
An array of nonuniform semiconductor diode lasers with supermode control for achieving a single-lobed farfield pattern is described. This is accomplished by spatially segregating the fundamental supermode from the other supermodes, tailoring the spatial gain profile as as to favor the fundamental supermode, and sufficiently increasing the intechannel coupling so as to bring about single-lobed farfield operation. In a preferred embodiment, this is achieved in a shallowly proton implanted, tailored gain, chirped laser array in which the widths of the lasers are varied linearly across the array.
