Abstract


A diode laser sensor based on absorption spectroscopy is developed for measurement of self-broadening coefficients for the three lines of v3 band of CO at high temperature. the spectra of CO at 6390.8152 cm-1, 6393.1767 cm-1 and 6395.4312 cm-1 at temperatures ranging from 323K to 873K with different pressures are recorded. The line widths are acquired by the line shape fittings based on Voigt function, and the collitional broadening coefficients and temperature dependences of the three lines are also derived.
