Abstract
Mount for semiconductor laser devices comprises thermally conductive anode and cathode blocks on either side of semiconductor laser device such as laser diode. Interposed between at least the anode block and the anode of the semiconductor laser device is a sheet of conformable electrically conductive material with high thermal conductivity such as pyrolytic highly-oriented graphite. In some embodiments, a second sheet of such electrically and thermally conductive conformable material is interposed between the cathode of the semiconductor laser device and the cathode block. The semiconductor laser device can be either a single laser diode or a diode bar having a plurality of emitters. A thermally conductive, but electrically insulating, spacer of essentially the same thickness as the laser diode or bar surrounds the diode or bar to prevent mechanical damage while still permitting the conformable material to be maintained in a compressed state and directing current through the laser device.
