摘　　要：研究了光场与级联型三能级原子依赖强度耦合系统,通过数值分析讨论了该系统原子偶极压缩特性.研究发现随着平均光子数n-值的增大,实现了三能级原子偶极算符的色散分量完全被压缩,吸收分量有部分压缩.这表明初始光场平均光子数n-对原子的偶极压缩有重要影响.The atomic dipole squeezing effects in the intensity-dependent coupling interaction between a three-level cascade atom and light field are studied by numerical calculation. The results show that two of the atomic dipole operator display squeezing effect, with the increasing of the value of n, one atomic dipole operator could be fully squeezed, n plays an important role in atomic dipole squeezing effects.
