Ξ型三能级原子与单模场耦合系统的腔场谱

Cavity Field Spectra for the Interaction System of a Ξ-type Three-level Atom with Single-model Field

研究了光学腔内单模场与Ξ型三能级原子相互作用系统的腔场谱,讨论了初始光场分别处于粒子数纯态、相干态和压缩真空态时的腔场谱结构。结果表明,光谱结构一般为8峰结构,并与初始光场的光子数分布与光强有关。

The cavity spectra for the interaction system of a Ξtype threelevel atom with singlemodel field were investigated when the field is initially in a pure number state,a conherent state and a squeezed vacuum state.It is shown that there appear symmetric eight peaks in the cavity spectra,whose structure depends strongly on the photon number distribution and intensity of initial light field.
