ABSTRACT:
A cooling device for laser diodes comprising a stem which comprises a 2 mm thick Cu substrate having thereon an array of grooves extending to the resonator length of a laser diode device with a width of 50 μm and a depth of 300 μm and a 100 μm thick Cu cover plate for hermetically sealing the grooved surface by, e.g. soldering. The groove contains a working fluid of deionized water filled under reduced pressure, forming a heat pipe. A plurality of heat pipes is created to form a heat pipe array. Forty GaN laser diode devices each having five light-emitting areas, each of which has an optical power of 100 mW, are mounted with junction-down on the upper surface of cover plate, forming a bar laser with a total output of approximately 20 W.
