Abstract

Using a distributed feedback diode laser, pressure induced self-broadening and shift have been measured for several transitions in the 2ν1+ 2ν2+ ν3band of CO2, centered at 1.573 μm. Foreign broadening and shift, with N2and O2as perturbing gas, have been measured for the most intense lines. The results for broadening have been compared with the data given by HITRAN molecular database and some discrepancies have been found, specially for air broadening derived from N2and O2broadening.
