RESONANT RADIATION OF ATOM IN SGUEEZED LIGHT FIELD
原子在压缩光场中的共振辐射

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.
