A self‐consistent code has been utilized in modeling a discharge‐pumped XeCl laser. The electron energy distribution function (EEDF) has been calculated using a time‐dependent Boltzmann equation. The effects of the secondary electrons produced by ionization on EEDF, rate coefficients, species densities, laser energy, and breakdown delay time have been examined by comparing different models in a wide range of discharge parameters. Efforts have been made at explaining the discrepancy in the breakdown delay time between simulation and experiment. It is found that the secondary electrons due to ionization play an important role in determining the breakdown delay time. Furthermore, the measured breakdown delay time can be well reproduced using the model presented in this work instead of increasing the total excitation cross sections of xenon.
