Abstract
The disclosed diode laser packages include a carrier having an optics-mounting surface to which first and second sets of collimating and turning optics are mounted. The carrier includes a heatsink receptacle medially located between the first and second sets. A cooling plenum has a diode-mounting surface and includes heatsink material disposed in the heatsink receptacle. The cooling plenum further has an inlet, an outlet, and a coolant passageway defined between the inlet and the outlet. The coolant passageway is sized to receive the heatsink material disposed in heatsink receptacle. Multiple semiconductor laser diode devices are each mounted atop the diode-mounting surface and positioned for bidirectional emission toward the first and second sets of collimating and turning optics. The multiple semiconductor laser diode devices are thermally coupled to the heatsink material through which coolant is deliverable by the coolant passageway.
