Gas discharge tube for an ion laser

摘要

In an ion laser having a discharge channel extending through a ceramic tube, a coil of thermal conductive material is placed around the ceramic tube and the tube and coil combination are inserted into a bore of a heat eliminating device. The tube, coil, and heat eliminating device are soldered to one another so as to provide clearance between individual turns of the coil, thereby providing good cooling characteristics and enhanced power of the laser without risk of breakage of the ceramic tube.
