For a typical laser gas discharge, the concentration and temperature of the most important plasma components at the end of the current pulse are calculated on the basis of given data for the tube radius, gas pressure, and energy input. Relating to a postdischarge time up to 1 s, the deionization, the association of the nitrogen atoms, the deexcitation of metastable molecules and the relaxation of the vibration temperature are investigated by means of simple balance equations. Finally the influence of plasma relicts on the following discharge pulse is discussed.
