Laser utilizing transitions between levels of paired CO2 modes

The possibility of achieving stimulated emission due to transitions between levels of paired CO₂ modes is considered theoretically. It is shown that the gain for the 03¹0–10⁰0 transition may reach 0.006 cm^–1 at T = 150°K if the CO₂:Ar composition is optimal (1:30) and the degree of ionization is n_e/n_CO2 = 3×10^–7.
