Absorption of 9.6-µm CO2 laser radiation by CO2 at elevated temperatures
Abstract
Transitions in CO2 gas induced by the absorption of 9.6 micron laser radiation at higher temperatures were examined. Several lines of the 9.6 micron 0011-0012 transition at temperatures between 296-625 K were studied, and the absorption coefficient was determined as a function of temperature. Additional trials were run to define the relative optical broadening coefficients due to He and N2 for the R16-R22 and P16-P22 transitions. The values obtained for the coefficients and the percentage contribution to calculated absorption coefficient at 620 K are provided.
