Abstract
The saturated absorption spectrum of D2 line in Cs was investigated using two diode lasers emitting at 852 nm. It was obtained in a 5 cm long Cs cell at room temperature. The frequency scale was calibrated using the beat note signal from a fast photodetector on which the two laser beams were combined. In order to eliminate the effect of the reference laser frequency drift, a two-laser beam optical arrangement producing the saturated absorption was used. A simple model giving the number of observed peaks and the frequency intervals between them was developed. The two spectra corresponding to the two ground state components of Cs were fitted using a Lorentz profile as a model function and the obtained frequency intervals were compared with the Cs atom hyperfine splittings.
