The correlation between the plasma resistance and the laser output parameters has been investigated in pulsed CO 2 — N 2 discharges. The strong increase of the discharge resistance during gas degradation can be explained on the basis of strong attaching gas components. In degraded mixtures a supression of discharge instabilities together with the restoration of the laser pulse energy is possible by increasing the reduced electric field E / N temporarily.
