Excitation rates of the stepwise excitation process via the Cd(II) ground state, Penning excitation by He excited atoms and other processes, are calculated for the upper and lower states of the 441.6 nm line under actual discharge conditions for laser action. The calculation uses previously measured values of particle densities, electron energy distribution functions and excitation cross-section data, and population densities of Cd(II) excited states measured more accurately in this experiment. The excitation mechanism of the 441.6 nm laser is clarified on a quantitative basis.
