  • Methods and apparatus for removing heat from a lasing medium of a solid-state laser assembly
    Patent number: 6768751
    Abstract: An apparatus for removing heat from a lasing medium of a solid-state laser assembly is provided that comprises a working fluid and at least one condensation surface defined by a housing in which at least a portion of the lasing medium is housed. The apparatus further comprises a coolant circuit and a wick disposed to distribute the working fluid in a liquid state over at least a portion of an outer surface of the lasing medium and to capture working fluid condensing upon the at least one condensation surface. During use, the wick distributes the working fluid in a liquid state over the at least a portion of the outer surface of the lasing medium. During contact with the at least a portion of the outer surface of the lasing medium, the working fluid evaporates and removes heat from the lasing medium. The working fluid in a vapor state contacts the at least one condensation surface, transfers heat to the at least one condensation surface, and condenses on the at least one condensation surface.
