Abstract

High power pulsed microwave techniques are electrodeless means for the excitation of high pressure gas discharges such as rare-gas halide gas mixtures. These techniques are alternatives to TEA-discharges driven by pulsed dc-currents for the excitation of lasers operating in the UV and infrared. However, there are problems concerning the interaction of guided microwaves with a high pressure discharge produced in a tube inserted in the waveguide structure.
