Abstract
The subject invention relates to a conduction cooled ion laser capable of producing higher output power. The device includes an insulated tube and a plurality of heat conducting members mounted in thermal contact with the wall of the tube. Primary and secondary ring gas barriers or shields project axially from the heat conducting members with the primary shield being located radially inward with respect to the secondary shield. The shields are mounted such that they axially overlap to define a reentrant configuration. The reentrant configuration allows for the operation of the laser at a higher power with the same voltage safety margin above the instability voltage.
