ABSTRACT:
A gaseous laser includes a gas discharge tube made of a comparatively thin-walled ceramic tube. Heat from the discharge is transmitted to the exterior tube by conduction through thin-walled, cup-shaped members which are bonded to the interior wall of the ceramic tube. The discharge cross-section is determined by apertures in sputter-resistant discs which are coaxially affixed to or formed on the cup members. Also coaxially affixed to the cup-members are cylindrical shields which control gas pumping within the tube. Gas return holes are provided in the cup-members.
