摘　　要：为了消除多能级原子饱和吸收光谱中的交叉共振峰,本文使用薄铷原子汽室来测量87Rb原子D2线5S1/2,F=2→5P3/2,F'的饱和吸收光谱.结果显示,随着铷原子汽室厚度的减小,饱和吸收谱线中交叉共振峰的幅度明显减小,有的甚至消失.同时,随着原子汽室的厚度的减小,必须提高其温度才能观察到明显的饱和吸收光谱.In order to eliminate the crossover resonance of Rb’s saturated absorption spectroscopy , thin Rb vapor cell was used to measure the saturated absorption spectroscopy （ SAS） of 5S1/2 ,F=2→5P3/2 , F′transi-tion of rubidium D2 line.The saturated absorption spectrum signals were analyzed. It is shown that reducing the thickness of vapor cell can result in the decrease of the relative intensity of crossover resonance , even the disap-pear of some crossover resonance. Reducing of the thickness of vapor cell will go with the higher temperature.
