Abstract

Kinetic calculations of the active medium of a Sr-vapor laser require knowledge of effective cross sections of the processes developing in a discharge plasma. We have calculated effective electron-impact excitation cross sections of SrI singlet levels using the Born approximation. The calculations were performed for the incoming electron energy lying in the range between the excitation threshold and 600 eV. The results obtained were compared with experimental and theoretical data known from the literature. The closest agreement was observed for the excitation cross section of the resonance 5p ¹P⁰₁ level (upper laser level for lasing at λ=6.45 µm). A number of the calculated effective cross sections for excitation of high-lying states are presented.
