The paper considers current-voltage characteristics of arc discharges in gas lasers on ArII and ArIII ions. Some peculiarities of electrical conductivity of plasma η-1 are identified, both theoretically and experimentally. It is shown that as you increase the current of arc discharge while decreasing the supporting discharge voltage, the electrical conductivity of plasma rises sharply. It is a contrary regularity of the standard current-voltage characteristics. Such a deviation from the standard electrical conductivity of plasma is likely to be an indicator of deteriorating laser design.
