Theoretical analysis of the stimulated emission spectrum of a pulsed electron-beam-controlled 12C18O2 laser

Calculations are made of the frequencies of transitions in the 01¹1-[11¹0, 03¹0] "hot" band of the ¹²C¹⁸O₂ molecule. These data are used in a theoretical analysis of the stimulated emission spectrum of an atmospheric-pressure ¹²C¹⁸O₂ laser. It is found that most of the radiation energy is concentrated in the IIP(18) and IIP(20) lines in the short-wavelength branch (λ≈9.3 μ) influence of the degree of enrichment of the carbon dioxide gas on the stimulated emission spectrum of a ¹²C¹⁸O₂ laser is discussed. It is found that single-frequency stimulated emission can be achieved due to the IIP(18) or IIP(20) transitions by altering the composition of the carbon dioxide gas in the active medium.
