ABSTRACT:
To provide more economical excitation of a high-power laser comprising a resonator having mirrors arranged in spaced, opposite relation to each other in the direction of a resonator axis and a beam path extending in both the direction of the resonator axis and a transverse direction perpendicular thereto, a gas-discharge volume permeated by the beam path and containing laser gas, and two facing wall surfaces extending substantially parallel to the resonator axis and to the transverse direction and enclosing between them and thereby delimiting the gas-discharge volume, it is propsoed that at least one wall surface be formed by a dielectric wall, that a microwave resonance structure separate from the laser gas in the gas-discharge volume be placed on the dielectric wall and have an opening facing the dielectric wall and bring about in an area of volume of the gas-discharge volume opposite the opening a microwave excitation of the laser gas, and that microwaves be introducible into the microwave resonance structure from a microwave source.
