Abstract

Measurements have been made of the small signal absorption of CO2 laser radiation by pure heated carbon dioxide at temperatures up to 615 K. Measurements were made of the P12 through P20 lines in the 001–100 absorption band. The absorption was higher on all lines measured than is predicted assuming no contribution from other lines. The absorption is predicted, however, when account is taken of contributions due to the 0111–1110 band.
