Abstract:

Alkali metal halide photodissociation lasers emit at the first resonance transitions of atoms. This allows using such lasers for the analysis of a number of metals in gaseous media by the absorption and resonance fluorescence method. In the first part of the work, the general principles and mechanisms of creating inversion at resonance transitions of alkali metal atoms during photodissociation of their halide molecules are considered. Data on wavelengths at the first resonance transitions of alkali metal atoms (Li, Na, R, Rb, Cs) are systematized. The main processes responsible for the formation of the spectral contour of resonance generation lines of photodissociation lasers are determined. Some features of the application of such lasers for sounding gaseous media are noted. The results can be used in the study of photodissociation generation at the first resonance transitions of alkali metal atoms.
