ABSTRACT:
A heat conducting structure in a discharge tube of an ion laser, that has high resistance to erosion due to sputtering comprises a discharge limiting member having an inner aperture, and a thin film of refractory ceramic coating areas near the inner aperture. The thin film of ceramic does not significantly retard heat flow out of the discharge into the heat conducting structure, but significantly increases resistance of the heat conduction structure to sputtering.
