Enission spectra Of aΞ-type three-1evel atom in a Kerr medium

We investigate the emission spectra of a Ξ-type three-level atom interacting with a single-mode optical field in an ideal cavity filled with a Kerr medium and discuss the structure of emission spectrum when the optical field is initially in a pure number state and a coherent state, respectively. It is shown that the structure of emission spectrum depends not only on the photon number distribution, but also on the strength of incident field and the coupling of Kerr medium to the field.

Emission spectra of a (?)-type three-level atom in a Kerr medium

We investigate the emission spectra of a (?)-type three-level atom interacting with a single-mode optical field in an ideal cavity filled with a Kerr medium and discuss the structure of emission spectrum when the optical field is initially in a pure number state and a coherent state, respectively. It is shown that the structure of emission spectrum depends not only on the photon number distribution, but also on the strength of incident field and the coupling of Kerr medium to the field.     

广义Kerr介质奇偶相干态中相位算符的压缩性质

利用S.M.Barbett和D.T.Pegg提出的测量相应算符，研究了存在广义Kerr介质时，奇偶相干态中测量相位的二阶和高阶压缩性质。着重讨论了广义Kerr介质的非线性阶数m对奇偶相干态中测量相位压缩的影响。结果表明：在广义Kerr奇偶相干态中，测量相位算符存在间歇性的偶数阶CS类压缩和双偶数阶CN类压缩，压缩的深度与非线性介质的阶数m、|α}^2及δ有关。
