  • This paper reports on investigating the ionization instability in active media of electric discharge non-chain HF(DF) lasers due to electron impact detachment of electrons from negative ions. This instability has been triggered in large volumes of SF6-based mixtures, spatially separated from electrodes, through the gas heating by a pulsed CO2 laser radiation. A self-organization phenomenon in a Self-sustained Volume Discharge(SSVD) on a laser-induced gas heating and resulting in formation of quasi-periodic plasma structures in the bulk of discharge gap is experimentally studied. Special attention is given to the evolution of these structures on changing the gas temperature and specific electric energy depositions. A plausible relation of the found self-organization effect to the electron detachment instability treated is discussed. Also suggested is the mechanism of moving a single plasma channel in working media of HF(DF) lasers owing to destruction of negative ions by electron impact.
