Gas laser
This patent describes a gas laser. It comprises: an outer quartz tube including two end cap assemblies fashioned from one or more materials, each characterized by a low thermal expansion coefficient that is substantially compatible with the thermal expansion coefficient of quartz; two mirror elements, disposed coaxially and secured respectively by the end cap assemblies; inner tube support means disposed with the outer tube; and inner tube coaxially disposed between the mirror elements, and supported by the inner tube support means; cooling means in thermally coupled relation with a central portion of the inner tube; and a pair of electrodes, each electrode proximate to a respective end of the inner tube.
