摘要
导出了介质中双模SU( 1 ,1 )相干态场与Λ型三能级原子非共振相互作用系统的态函数 ,研究了场模失谐量、克尔介质以及原子初态对场的互关联函数和MandelQ参量的影响 结果表明 :失谐量将削弱光场两模的关联性 ,并影响场模光子数的统计分布 ;当SU( 1 ,1 )场两模间的光子数之差增大时 ,失谐量对它们产生的影响变得更弱 ,此时克尔效应的影响变得明显 。
The state function has been derived for the non resonance interaction of a Λ type three level atom with two mode SU(1,1) coherent states in a Kerr medium.It is studied that the influence of detuning,Kerr medium and initial atomic coherence on them two mode intersity correlation function and the parameter Mandel Q.The results show that the detuning weakens the correlation intersity and affect the photon statistical properties.With incresasing the photon difference of the two mode cavities,the influence of the detuning on them become weak,at the same time,Kerr effects become evident and make the correlation and photon statistical properties steady.
