On the temperature dependence of collisional linewidths of the 10{sup 0}0 - 00{sup 0}1 laser transition in the CO{sub 2} molecule

On the temperature dependence of collisional linewidths of the 10{sup 0}0 - 00{sup 0}1 laser transition in the CO{sub 2} molecule

Unsaturated absorption coefficients in pure carbon dioxide and CO{sub 2} - N{sub 2} and CO{sub 2} - He binary mixtures are measured at a pressure of 100 Torr in the temperature range of 300-700 K using a frequency-stabilised tunable CO{sub 2} laser. The relative coefficients of collisional broadenin...

Zusammenfassung:Unsaturated absorption coefficients in pure carbon dioxide and CO{sub 2} - N{sub 2} and CO{sub 2} - He binary mixtures are measured at a pressure of 100 Torr in the temperature range of 300-700 K using a frequency-stabilised tunable CO{sub 2} laser. The relative coefficients of collisional broadening caused by N{sub 2} and He buffer gases and their temperature dependence are determined for the R(22) absorption line (10{sup 0}0 - 00{sup 0}1 transition) of the CO{sub 2} molecule.
