Abstract
A diode-laser bar package includes a water cooled metal heat-sink. An electrical-insulator-plate is bonded to the heat-sink with a soft solder. A metal sub-mount and a first electrode are bonded, spaced apart, on the electrical-insulator-plate. A solder-bridge fills the space between the first electrode and the sub-mount. A diode-laser bar is bonded to the sub-mount. A second electrode is bonded to the first electrode with an electrically insulating bond. Electrical connection between the second electrode and the diode-laser bar is made by a plurality of wire-bond electrical leads.
