摘要
研究了铯饱和吸收光谱随抽运光强度变化的情况，特别是６２Ｓ１／２Ｆ＝４→６２Ｐ３／２Ｆ′＝５的谱线的变化行为．在线偏振光抽运、线偏振光检测的情况下，计入所有相关的Ｚｅｅｍａｎ子能级之间的跃迁，考虑光抽运与饱和效应的共同作用，运用ＲｕｎｇｅＫｕｔａ法则求解粒子数方程，计算得出的饱和吸收谱与实验结果符合得较好．
The dependence of Cs saturated absorption spectra on the intensity of pumping light,especially that of the spectrum of 6 2S 1/2 F=4→6 2P 3/2 F′=5,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 Zeeman sublevels of the hyperfine structure.The theoretical calculations were in good agreement with the experimental results.
