Abstract
A broad area semiconductor diode laser device includes a multimode high reflector facet, a partial reflector facet spaced from said multimode high reflector facet, and a flared current injection region extending and widening between the multimode high reflector facet and the partial reflector facet, wherein the ratio of a partial reflector facet width to a high reflector facet width is n:1, where n>1. The broad area semiconductor laser device is a flared laser oscillator waveguide delivering improved beam brightness and beam parameter product over conventional straight waveguide configurations.
