Abstract

A laser diode device includes a thermally conductive substrate that has a planar surface for dissipating ambient heat, and a plurality of laser diodes situated thereon, each of which includes at least one epitaxial layer that is situated on a side of the laser diode facing the substrate. The laser diodes are each electrically activated via an electrically conductive coating situated between the at least one epitaxial layer and the substrate. The substrate includes a plurality of metallized cavities that accommodate the plurality of laser diodes so that the plurality of laser diodes have an essentially uniform height above the substrate.
