Radiation power control of the industrial CO2 lasers excited by a nonself-sustained glow discharge with regard to dissociation in a working gas mixture

摘要

Highlights ? Degradation of the gas mixture must be taken into account in the control system. ? Gas mixture chemical equilibrium must be obtained before the laser operating mode. ? Initial ionization frequency of 740Hz for 50s must be supplied for the laser. Abstract The action of a working gas mixture degradation related to the plasma chemical reactions in a glow discharge on the laser output power of the molecular laser excited by a nonself-sustained glow discharge has been studied by the example of an industrial laser of “Lantan” CO2 laser series. It was found that the laser power overshoot when operating on
