Zusammenfassung:The aim of this work is to analyze the high-precision measurements of the profile of spectral lines using near-IR diode lasers (DLs). To this end, a multichannel DL spectrometer of high spectral resolution has been developed, calibrated, and put into operation. Special attention is paid to the deviation of the gases studied from ideal behavior. Real CO 2 gas and a mixture of real CO 2 :SF 6 gases are used as models.
