Kerr介质中与双模光场作用的三能级原子的偶极压缩效应

研究了一位于高QKerr介质腔中与双模相干光场作用的Λ型三能级原子的偶极压缩效应，通过数值计算，讨论了Kerr效应和单光子失谐量对原子偶极压缩的影响。结果表明，随着Kerr效应的增强，原子偶极压缩程度减弱，以至消失，而压缩时间也越来越短。但随着单光子失谐量的增加，原子偶极压缩随之增加，其压缩时间延长。

Dipole Squeezing Effects of a A-type Three-level Atom Interacting with a Two-mode Coherent Field in a Kerr-like Medium

The dipole squeezing effects of a A-type three-level atom interacting with a two-mode coherent field are investigated. Through the numerical calculations, the influences of the Kerr effect and the one-photon frequency detuning on the atomic dipole squeezing are also discussed. It is shown that the atomic dipole squeezing reduces up to disappearence and that the time of the squeezing becomes short with increasing the Kerr effect, but that the atomic dipole squeezing raises and that the time of the squeezing becomes long with increasing the one-photon frequency detuning .
