ABSTRACT:
An electric discharge gas laser has a turbulence generator inserted in the flow path of the gas upstream of the optical cavity. The turbulence generator is illustrated as a screen. The turbulence is also disclosed as resulting from a vortex-causing blade inserted in the gas conduit. The turbulence resulting in the gas flow provides energy and specie diffusion to the outer walls at a rate relatively faster than laminar (molecular) diffusion, thereby permitting stable operations of the diffuse electric discharge at relatively higher powers.
