Abstract

Due to its fast periodic voltage variation the rf-discharge has a lower demand on electrical field strength for achieving a self sustained discharge as compared to a dc-discharge. As a consequence higher values of electrical power density can be deposited in the gas at enhanced uniformity. Low electrode losses and reduced gas degradation increase the efficiency of this technique. Experimental performance data of transverse and axial flow lasers are presented which demonstrate the large potential of rf-excitation for cw and modulated operation.
