Abstract
A diode pumped slab laser (DPSL) that is cooled by a capillary heat pipe cooling apparatus. The DPSL contains a diode array that is cooled by one or more capillary evaporators that are adjacent to the diode array of the DPSL or contained within a thermally conductive substrate surrounding the diode array of the DPSL. The capillary evaporators convert the liquid phase of a working fluid to a vapor phase which is circulated to a condenser. The condenser causes the phase of the working fluid to change to a liquid phase which is then drawn back to the capillary evaporators by the evaporation of the working fluid within the capillary evaporator. In one embodiment, the diode array is interleaved with heat sink strips that conduct the heat away from the diode array strips and toward a closely spaced capillary evaporator wick facing the diode array. The vapor is carried away from the diode array in the channels formed between consecutive heat sink strips.
