摘要
本文应用随机统计理论方法获得了一二能级原子系综在多模压缩光驱动下的共振辐射光谱。对应于光场起伏的不同压缩程度,辐射光谱的中峰出现亚自然线宽与超自然线宽现象。它的边峰在任意情况下都被展宽,而且当光场起伏的压缩方向与光场振幅的相干激发方向不平行或不垂直时,辐射光谱均呈现不对称分布。
In the paper, applying the stochastic statistical methods, we obtain the resonant radiation spectrum of a two-level atom ensemble driven by multimode squeezed light. Co-responding to different squeezing degrees of the quantum fluctuations of the driving field, the central peak of radiation spectrum exhibits subnatural--and supernatural-linewidth phenomenon, and in all cases the side peaks are broadened. The positions of the side peaks and the character of symmetry of radiation spectrum depend upon the coherent excitation direction and the squeezing direction of the driving field.
