Abstract:
A semiconductor laser diode array comprising:a plurality of laser diode bars aligned in an array so that light paths are generally parallel; a plurality of electrically conductive submounts, disposed between said laser diode bars; a pair of opposing electrodes connected to two of said plurality of laser diode bars; a plurality of flexible electrically conductive spacers disposed between said laser diode bars and said submounts, said spacers formed from a compliant material having a hollow cross- section to relieve stress on said laser diode bars; a thermally conductive substrate for carrying said plurality of laser diode bars, said plurality of electrically conductive submounts, and said electrodes, and receiving heat generated by said laser diode bars; and a plurality of non-fluxed solder preforms disposed adjacent said laser diode bars; and said thermally conductive substrate for providing a continuous path therebetween when heated to a point to cause reflow.
