ABSTRACT:
Apparatus for extracting heat from objects such as a slab laser having an accessible flat surface subject to being heated and including a flat strip of material, preferably made from wafer grade semiconductor, such as silicon or gallium arsenide, and mounted in close proximity to the surface so as to leave a small gap therebetween of uniform thickness over an area of said surface to be cooled. A still gas fills the volume of the gap which is sufficiently small that the gas serves as an effective heat transfer medium from said surface to said strip from which heat is transferred to a medium mounted in thermal contact with the strip on the side away from said surface being cooled. The invention has particular application to the cooling of slab lasers.
