THE DEPENDENCE OF Cs SATURATED ABSORPTION SPECTRA ON THE INTENSITY OF PUMPING LIGHT

The dependence of Cs saturated absorption spectra on the intensity of pumping light, especially that of the spectrum of →′, was measured and calculated. When the pumping light and probing light were linearly polarized, the relative magnitudes of the resonance signals were calculated by solving a set of rate equations with Runge-Kutta algorithm, taking into consideration the optical pumping process and the saturation in the Zee-man sublevels of the hyperfine structure. The theoretical calculations were in good agreement with the experimental results.
