Abstract
High-precision measurements of the spectral-line profile using near-IR diode lasers (DLs) have been performed, and the measurement results have been analyzed. To carry out these measurements, a multichannel DL spectrometer with a high spectral resolution was developed, calibrated, and put into operation. Particular attention has been paid to the deviation of the gases under study from ideal behavior. CO2 of natural isotopic composition was chosen as a model gas.
