CW high-pressure tunable CO2 laser with a mixture of CO2 isotopes

The qualitative theory of the CO 2 laser at atmospheric pressure was developed. Investigations of a CW CO 2 laser at high pressure with conventional and waveguide resonators and obtaining CW oscillation in the mixture of three isotopic molecules, 12 C 16 O 2 , 12 C 16 O 18 O, and 12 C 18 O 2 , are reported. The problem of building a super-high-resolution spectrometer on the basis of a CW high-pressure CO 2 laser with mixed isotopes is discussed.
