Abstract

A diode laser sensor based on absorption spectroscopy has been developed for the measurement of spectroscopic parameters of the R(50) line at 5007.787cm^-1 (20012<-00001 band) of CO₂. Survey spectra of the CO₂ R(50) line of CO₂ - CO mixture gas with 49.82% CO₂ were recorded at different temperatures and pressures through a high temperature measurement system using tunable diode laser absorption spectroscopy. High-resolution measurements of the CO₂ R(50) line shape were used to determine collisional broadening full-width of CO₂ by CO as a function of pressure and temperature. The collisional broadening coefficients were obtained at temperatures between 323K and 1873K, and the temperature dependent coefficient of the collisional broadening full-width of CO₂ by CO was calculated. These parameters are supplement and improvement to the existing database. They are helpful for the detection of CO₂ concentration in combustion diagnosis to ensure the accurate inversion of CO₂ concentration in the combustion process.
