ABSTRACT:
A gas laser includes a plurality of electrically conductive electrodes contained within a hollow housing that contains a laser gas medium. The electrodes surround and define a laser bore in which a plasma is excited by the electrodes. Each of the electrodes defining the laser bore has an ungrounded electrical potential that provides improved laser gain at a lower gas temperature. Each of the electrodes may be driven with a controlled, varying electrical potential, such as a radio frequency electrical potential.
