ABSTRACT:
A gas laser having a segmented ceramic laser tube in which at least one thermally conducting, electrically insulating sleeve fits over the peripheral edges of segment interfaces. Coolant, such as tap water, passes in direct contact with the outer surface of the sleeve, but is excluded by the sleeve from corrosive contact with metal bonding at segment interfaces. A single sleeve may cover the entire length of the tube or each interface may be covered by a sleeve. A reservoir sleeve may fit over a portion of a gas reservoir, with coolant passing in direct contact with the outer surface of the reservoir sleeve. A cathode and anode at opposite ends of the tube sustain a gas discharge, while a resonant optical cavity aligned with the tube produces lasing action.
