Absorption Coefficient Measurements of CO2 HDO-N2, and CH4-Air Using a DF Laser

Abstract : The report presents measurements of the absorption of HDO-N2 mixtures when illuminated with a DF laser operating on the 3-2 P(6) to P(8) lines. Similar data is presented for pure CO2 and the 2-1 P(8) DF line. Measurements of CH4-Air mixtures are presented for the 2-1 P(6) - P(8) DF lines.
