rotating wave approximation

using electric dipole moment and the rotating wave approximation and matrix theory, the dispersion and absorption properties of the quasi-lambda four-level system driven by different relative phase are investigated on the condition of the interaction representation.

在相互作用表象下，运用电偶极矩和旋转波近似及其密度矩阵方程理论，探讨了准∧型能级系统中相干光场之间的不同的相对相位对探测光场的色散和吸收的影响。

Finally, we make a comparison of our results with those under the rotating wave approximation.
