Abstract
A laser system having a high power output and a large volume gaseous discharge has a plurality of electrodes at each end of a channel to establish a plurality of discharges and a housing arranged to provide a continuous recirculating lasing gas flow through the channel. An ejector connected to a main circulating pump is fixed to discharge into the recirculating lasing gas flow adjacent the channel to mix lasing gas streams and cause diffusion of the gas and thereby provide a uniform plasma flow in the channel. In one embodiment, magnets are arranged to surround the channel to eliminate thermal instabilities, if they arise, and to further homogenize the lasing gas streams and insure their uniformity.
