| 摘 要： | 采用数值计算方法研究了强相干初态光场与级联型三能级原子相互作用中原子的偶极压缩效应结果表明:级联型三能级原子偶极算符的两个正交分量均呈现出周期性的压缩现象,原子存在偶极压缩,且压缩的最大深度比弱场作用情况下要深得多;随着n值的不断增大,偶极算符两个正交分量的振荡频率随之增大,场与原子的非线性耦合越来越强,且振荡重复地出现复苏缩现象.

| Abstract: | The atomic dipole squeezing effects in the interaction of a three level cascade atom with strong coherent field of initial state are studied by numerical calculation.The results show that the both of the two normal components of the atomic dipole operator display squeezing effects periodically,this means that the atomic dipole squeezing can be exhibited,and the maximum value of squeezing under strong field is more greater than that under weak field;with the increasing of the value of n,the nonlinear coupling between the field and the atom is getting stronger and the stronger,and the phenomenon of revival shrink will arise repeatedly. |
