Hill, A E

This patent describes a laser system having a high power output. It comprises an enclosing housing, a gas lasing medium in the housing, a laser channel in the housing, means for providing continuous recirculating flow of the gas lasing medium through the housing and the channel, a plurality of electrodes at the upstream end of the housing adjacent one end of the channel, a plurality of electrodes at the downstream end of the housing adjacent the other end of the channel, a source of voltage connected to the electrodes for establishing and maintaining discharges in the channel, diffusing means to provide a uniform plasma flow in the channel and to provide a pressure rise to balance the pressure drop from recirculating flow through the housing and channel, and means to draw forth a beam of light energy from the channel. The diffusing means are comprised of disposed downstream from each respective upstream electrode for mixing and diffusing gas streams into the laser channel.
