Characteristics of the electrical discharge and power extraction in gas transport CO2 lasers
Abstract
Experimental results concerning electrical discharge and power extraction in gas transport CO2 lasers are presented. Both the multielement cathode-continuous anode and the continuous cathode-multielement anode (CCMA) structures are compared with regard to discharge stability, power dissipation in electrodes, and current-voltage characteristics of the discharge. For the CCMA structure with the cathode shifted to the opposite side of the gas flow direction, the stability limit of the discharge was 14 kW, and at a 10 A current discharge, gas mixture CO2-N2-He = 2.5:14:25 torr, the power dissipated in the continuous cathode was 3 kW, and 170 W in the multielement anode.
