Abstract
A method and apparatus for combining light output from multiple laser diode bars is disclosed. The apparatus includes two laser diode bars and a mirror arrangement placed between the laser diode bars. The mirror arrangement reflects the light output from the laser diode bars into a preferred plane and a preferred direction. The mirror arrangement is preferably comprised of metal mirrors. Alternative mirror assemblies disclosed are based on prisms. An alternative mirror disclosed includes a cylindrically concave surface for collimating or focusing an individual laser beam.
