三能级原子在双模激光场作用下的偶极压缩效应

DIPOLE SQUEEZING OF A THREE LOVEL ATOM UNDER THE INTERACTION OF A TWO MODE FIELD

应用量子电动力学理论，研究了三能级原子在双模激光场作用下的偶极压缩效应．结果表明，在弱光场作用下，三能级原子呈现明显的偶极压缩效应。

By use of the theory of quantum electrodynamics, we have studied the dipole squeezing of a three level atom interacting with a two mode coherent field. The results show that the dipole squeezing of the three level atom appears clearly under the interaction of the weak field,the two mode field intensities and the atem field eeupling constants have a strong effect on the dipole squeeing .
