Abstract
The method of sub-Doppler fluorescence spectroscopy is proposed, which is based on the features of the narrowing with time of the velocity distribution of optically excited atoms (molecules) of a rarefied gas medium in a thin cell after exposure to a sufficiently short light pulse. Changes in the established sub-Doppler resonances with time as well as the essential dependence of these resonances on dimensions of the gas cell are analyzed.
