Patent ID: 7515346

Claim:
A diode-laser module, comprising: a metal heat-sink having first and second opposite surfaces parallel to each other and an edge and a thickness; the heat-sink having cut-out region in the edge thereof, with the cutout region arranged to form first and second open-sided recesses in the respectively the first and second surfaces of the heat sink, with each recess having a depth less than the thickness of the heat-sink and wherein each recess has a width extending parallel to said edge and wherein the width of the first recess is less than the width of the second recess; a thermally conductive, electrically insulating sub-mount having first and second opposite surfaces, the sub-mount being bonded to the heat-sink in the second recess such that the first surface of the sub-mount faces into the first recess of the heat-sink and the second surface of the sub-mount faces into the second recess of the heat-sink; and a diode-laser bonded to the first surface of the sub-mount in the first recess of the heat sink and arranged to emit a diode-laser beam from the module via the open side of the first recess.
