Abstract
A high frequency cross-flow gas laser has a tubular conduit divided into a multiplicity of gas flow sections with gas inlets adjacent each of the mirrors therein and outlets therebetween. A pair of electrodes is provided along each flow section to produce a high frequency electrical discharge in the lasing gas mixture, and a cooler is used to chill the gas withdrawn from the conduit for recycling thereto. The electrode pairs are desirably radially rotated relative to one another to produce uniformity of the energy discharge across the cross-section of the lasing gas mixture.
