We investigate the features of the spontaneous emission spectra in a cold five-level atomic system coupled by a single elliptically polarized control field. We use wave function approach to derive the explicit and analytical expressions of atomic spontaneous emission spectra. It is shown that some interesting phenomena such as spectral-line enhancement, spectral-line suppression, spectral-line narrowing, spectral-line splitting and dark fluorescence can be observed in the spectra by appropriately modulating the phase difference between the righ...

我们在由单个椭圆形地极化的控制域联合的一个冷五水平的原子系统调查自发的排放系列的特征。我们使用波浪功能途径导出原子自发的排放系列的明确、分析的表情。它被看那一些有趣的现象象光谱线的改进那样，光谱线的抑制，光谱线的变窄，光谱线的切开和黑暗荧光能在系列被观察由适当地 modulating 之间的阶段差别右边循环地( LHC )并且左边( RHC )循环地极化了椭圆形地极化的控制域和外部磁场的紧张的部件。排放的数字达到顶点，熄灭荧光的点的位置能也被控制。而且，我们建议 ultracold 87Rb 为试验性的观察的原子系统。这些调查可以在高精确的光谱学发现应用。
