劣腔内压缩真空光场驱动的二能级原子的荧光光谱

The Fluorescence Spectrum of a Two-level Atom Driven by a Squeezed Vacuum Light in a Bad-cavity Limit

本文计算了劣腔内一受压缩真空光场驱动的二能级原子的荧光光谱及共二阶关联函数。我们发现这种荣光光谱具有单峰结构，它由两不同线宽、不同高度的谱线成分组成，两成分的线型都是洛伦兹线型。荧光的二阶关联函数表明，这种荧光具有光子反聚束效应。

The fluorescence spectrum and the second order correlation function of a two-level atom driven by a squeezed vacuum light in a bad-cavity limit are investigated. Wefind that the fluorescence spectrum exhibits one peak structure which contains two partsof different line-widths and heights- The second order correlation function indicates thefluorescence exhibits photon antibunching effect.
