ABSTRACT:
A hollow metal member which holds a mirror of an optical resonator in a gas laser tube is electrically and mechanically connected with a hollow cathode by a spring. The spring is positioned either outside or on the inner surface of the hollow metal member and elastically forces one end of the cathode against the inner wall of the hollow metal member.
