ABSTRACT:
A conduction cooled solid state laser comprises a laser rod and a pump lamp within a pump cavity in a housing constituting a heat sink, the remote exterior surfaces of the rod and lamp being covered by highly reflective metal foils in intimate contact with those surfaces and backed by a thermally conductive material between the foil and housing that is selected to provide a tailored thermal impedance. The foil acts as a highly efficient reflector and as a thermal contact element between the heat source (rod or lamp) and backing material, the latter, in either solid or fluid form, being selected to provide the desired thermal impedance between the source and sink to optimize component temperatures. The optically reflective and the heat transfer functions of the pumping operation are essentially separate from each other, enabling selection of materials for these respective functions to enhance performance of the laser and substantially simplify its construction.
