ABSTRACT:
To improve the power transfer of a glow discharge between a cathode (3) and an anode (4) in a glow discharge space (2), through which a laser-active is being passed (5) at high speed, the cathode is constructed to have a rotating surface, projecting through slits (8) of the walls (1) defining the discharge space into the discharge space, the tangential or surface speed of the cathode (3) being at least approximately equal to the flow speed of the gas, so that the gas will flow along the cathode in essentially laminar, linear flow, thereby avoiding turbulence at the surface and instabilities in the glow discharge.
