Abstract
A laser with a heat transfer system and method of making the same using electrodes. The heat transfer system draws heat from the electrodes which have internal electrode surfaces adjacent to a lasing medium of the laser. Cooling of the electrodes helps to maintain proper operating temperature for the lasing medium. The heat transfer system utilizes thermally conductive material positioned between external surfaces of the electrodes and internal surfaces of a housing that contains the electrodes and the lasing medium. Since the thermally conductive material adds capacitance to the laser system, inductance may be added for compensation depending upon the amount of thermally conductive material used. Options exist for positioning and applying the thermally conductive material between the electrodes and housing including press fitting strips of the thermally conductive material in depressions in the electrodes, and spray coating the thermally conductive material onto the electrodes, or the housing, or onto both the electrodes and the housing.
