A heat spreader structure includes a high power laser with an epi side and an emitting facet. A vapor chamber includes a housing defining an inner vapor cavity and a wick positioned in the vapor cavity to define an evaporation area on one side of the cavity, a condensation area on an opposite side of the cavity, and fluid communication between the condensation area and the evaporation area. A space defined between the evaporation area and the condensation area. The wick includes a porous powder sintered to inner surfaces of the sealed cavity to hold the porous powder in position. The epi side of the laser is coupled to the one side of the vapor chamber and heat removal mechanism is coupled to the opposite side of the cavity.
