Claim 19:
20. A method for cooling a laser diode system, the method comprising:
providing a substrate, a laser diode emitter supported on a surface of the substrate, and a facet at one end of the laser diode emitter from which a laser beam is emitted;
arranging a cooling subsystem in contact with the surface of the substrate of the laser diode emitter;
flowing a cooling fluid through elongated channels formed between fins of the cooling subsystem, where the fins project from a base portion of the cooling subsystem and are spaced laterally apart from the substrate; and
wherein the cooling fluid flows over the facet of the at least one laser diode emitter and into the elongated channels.
