Abstract
A laser diode package includes a laser diode, a cooler, and control circuitry, such as an integrated circuit. The laser diode is used for converting electrical energy to optical energy. The cooler receives and routes a coolant from a cooling source via internal channels. The cooler includes a plurality of ceramic sheets. The ceramic sheets are fused together. The ceramic sheets include traces or vias that provide electrically conductive paths to the integrated circuit. The control circuitry controls the output of the laser diode, e.g. the output at each of the laser diode's emitters. Multiple laser diode packages are placed together to form an array.
