The results are presented of theoretical and experimental investigations of the gain and emission spectrum of a TE laser utilizing a mixture of isotopically substituted 12CO2 and 13CO2 molecules. It was found that, in a wide range of active-medium pressures (p = 100–3500 Torr) and excitation levels (T3 = 1200–2400 K), a gas mixture such the concentration of 13CO2 (x13) and 12CO2 (x12) molecules satisfied the condition x13/(x13 + x12) 0.35–0.45 emitted one or several lines in the wavelength range between 11.11 and 11.22μ [between P(16) and P(26) in the 0001-1000 band of the 13CO2 molecule] in a laser with a nonselective resonator. The lasing efficiency was approximately equal to that for 12CO2. The results of calculations were in good agreement with the experimental data. |
