Abstract
A gas laser includes a pair of subsidiary electrodes to form a sharpening gap. These subsidiary electrodes are located within the envelope of the laser so as to be exposed to the same gas or mixture of gases that flow between the main electrodes and support the main lasing action. The efficiency of the laser and the lifetime of the electrodes of the sharpening gap are thereby improved, together with other advantages.
