Abstract
An ion laser is described having an anode construction which has no special configuration specifically designed to accommodate differential thermal expansion between it and a ceramic tube. The anode includes a radially thick first portion for good thermal conductivity and a thin-walled sleeve integral therewith extending beyond the tube to provide an exterior surface for electrical connection. The radially thick first portion provides desired thermal conductivity in the radial direction while the thin-walled sleeve acts to resist axial thermal conductivity. The anode is brazed to the interior cylindrical surface of a ceramic cylinder providing part of the tube, with a portion of its exterior surface extending beyond the cylindrical portion to be exposed externally for electrical connection. A ceramic end sleeve is brazed within the interior of the thin-walled portion of the anode to structurally support the same.
