Abstract
In a laser device having a laser medium and a laser pumping device associated therewith the improvement including an apparatus for efficiently dissipating heat generated in the laser medium to maintain the laser medium at a more suitable operating temperature, the apparatus including an elongated closed ended heat pipe having a first portion in closely spaced proximity and in heat conductive relationship to the laser medium and a second remote end portion in heat conductive relationship to a heat sink, the heat pipe having an outer conductive layer with a coating of a fluid absorbing material positioned therein and forming a passage therethrough, and a heat transfer fluid positioned in the heat pipe and absorbed by the absorbent material, the absorbed fluid adjacent to the laser medium heating when exposed to the heat generated in the laser medium whereby the fluid moves through the heat pipe to a remote location for conduction of the heat therein into the heat sink.
