A quantitative theory is proposed for calculation of the state of the plasma and various electronic excitation rates in high-current low pressure discharges typical of noble gas ion laser operation under quasi-steady state, constant-pressure or constant-density conditions. At present, only wall-confined discharges in the absence of any externally applied magnetic fields is considered. For simplicity, multiple ionization is also neglected. The discharge is formulated as a three-temperature problem with significant axial electron drift. It is found that the natural similarity parameters in such a discharge are pRthe product of the total filling gas pressure p and the discharge tube radius R, and jR the product of current density j and the tube radius.
