Abstract
A number of beams that can be coupled into an optical fiber can be increased using emitted beams having greater divergence, thus providing increased beam power. Alternatively, with a fixed number of emitters, total optical power can be maintained with fewer beams in an output beam with a smaller numerical aperture.
