High-Precision Spectroscopy with Diode Lasers. Deviation of Gas from Ideal Behavior

Аннотация

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.
