CW high-pressure tunable CO2laser with a mixture of CO2isotopes

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,

2
laser with mixed isotopes is discussed.
