Electron energy distribution functions (eedf) in CO 2 laser discharge (He—CO 2 —N 2 —CO mixture) have been calculated by solving the Boltzmann equation in the presence of given concentrations of excited (vibrational and electronic) states. The results show a well structured eedf as a result of second kind collisions coming from metastable electronic states of N 2 and He as well as a strong dependence of rate coefficients for CO 2 dissociation and for the ionization of the different species.
