Abstract
A laser diode array having a grooved substrate with one or more laser diode bars disposed in the substrate grooves. When mounted in the substrate, the bars emit light in a direction perpendicular to the minor surface of the substrate. Additional structure is provided to channel the light output of the array. The substrate may be comprised of a number of materials, including: ceramic; semiconductor; crystal, such as diamond; doped ceramic; doped semiconductor; doped crystal; composites, composed of conductive upper layers and nonconductive lower layers, or the like. In certain embodiments metallization is provided in the grooves for purposes of conduction and for attachment of the laser diode bars. In certain embodiments metallization may be provided in the grooves for purposes of attaching the laser diode bars securely; the conductive nature of the substrate providing the required electrical conductivity.
