The voltage-current characteristics of a UV preionised CO2 laser operating at pressures ≲13 atmospheres have been investigated and the quasi-steady glow and breakdown fields measured. The discharge resistivity has been found to be a function of the applied excitation field and a simple model has been developed to explain the results obtained.
