Abstract

A laser system is disclosed in which the laser medium is operated at high pressures, for example, at pressures of about 3 atmospheres or above, to yield high performance. High pressure operation is achieved by employing a two or more stage containment system. In one preferred embodiment, a first containment system, housing high voltage components, can be pressurized to about 2 atmospheres or more with a high dielectric constant gas to permit low inductance circuitry. The laser head assembly is encased within a second containment vessel and further pressurized to about 3 atmospheres or more. The laser head assembly can also include a flow nozzle and ventilated electrodes to reduce stagnant pockets and eddy currents in the circulating laser medium.
