ABSTRACT:
An active gas based on CO.sub.2 penetrates under pressure into a discharge chamber (20) via injection orifices (10) formed through the upstream face of said chamber. These orifices leave considerable solid portions (22) about themselves in said face such that the gas forms jets which diverge up to an outlet grid (12) constituting a common anode. Cathodes (8) are individually powered by a block (14) and give rise to discharges which are widened on the edges of said jets by large-amplitude gas recirculation currents, thereby increasing the electrical power injected. The invention is particularly applicable to power lasers.
