Abstract:
1. A laser diode array having at least a first laser diode package and a second laser diode package, each of first and second laser diode packages comprising: a laser diode for converting electrical energy to optical energy at a plurality of emitters; a cooler for receiving a coolant from a cooling source, the cooler comprises a plurality of ceramic sheets and an exposed sheet, the ceramic sheets being fused together and the exposed sheet being attached to a top ceramic sheet of the plurality of ceramic sheets, the plurality of ceramic sheets having apertures for defining internal channels for routing the coolant, at least the exposed sheet including individual electrical traces, the laser diode being mounted on the cooler and each of the traces being in contact with the laser diode to provide power to a corresponding one of the emitters of the laser diode; and an integrated circuit mounted on the exposed sheet of the cooler, the plurality of traces leading from the integrated circuit to the plurality of emitters, the integrated circuit being electrically coupled to the traces to control the electrical power supplied to each emitter by the corresponding trace; and wherein the integrated circuit on the first laser diode package has a thickness that is substantially the same as the laser diode on the first laser diode package such that the second laser diode package is positioned against both the integrated circuit and the laser diode of the first laser diode package.
