ABSTRACT:
In a gas laser excited with pulsed microwave energy, a running gas discharge is generated in a waveguide, this discharge placing the gas in its excited condition, and expiring after migrating through the waveguide. The microwave energy is supplied at one end of the waveguide, and a short-circuit element is disposed at the other end of the waveguide, with an igniter attached in proximity to the short-circuit element so that the gas discharge, and thus the excitation of the laser gas always begins at the end of the waveguide at which the short-circuit element is disposed. This structure is especially suited for CO.sub.2 lasers.
