摘要
使用频率可扫描的窄线宽半导体激光，通过共振吸收方法获得强磁场下Ｃｓ（６Ｓ_１／２→６Ｐ_１／２）在不同种类和不同压力的惰性气体中的吸收线型。利用Ｖｏｉｇｔ线型公式对不同的实验线型进行拟合，从而求得压力增宽系数。实验表明，在低于１．３３×１０￣４Ｐａ范围内，碰撞增宽与压力成线性关系。
Using semiconductor laser of narrow line width, we obtain the absorption spectral profiles of D_1 (6S_1/2 → 6P_1/2) of Cs in a high magnetic field in different kinds and at different pressures of noble gases. It is shown that the broadening is linearly proportional to the foreign gas pressure lower than 1. 33 × 10￣4Pa in our experiment. We get coefficients of broadening by fitting to the Voigt profile.
