ABSTRACT:
A laser system includes a laser diode source with a plurality of output facets. The laser diode source produces a divergent output along an emission path. A microlens is optically coupled to the diode source. The microlens receives the divergent output along the emission path and modifies the divergence of the output in a high numerical aperture direction of the microlens A power source is coupled to the laser diode source.
