We interpret cooperative scattering by a collection of cold atoms as a multiple-scattering process. Starting from microscopic equations describing the response of N atoms to a probe light beam, we represent the total scattered field as an infinite series of multiple-scattering events. As an application of the method, we obtain analytical expressions of the coherent intensity in the double-scattering approximation for Gaussian density profiles. In particular, we quantify the contributions of coherent backward and forward scattering.
我们将一群冷原子的合作散射解释为一种多重散射过程。从描述N个原子对探测光束响应的微观方程出发，我们将总散射场表示为多重散射事件的无穷级数。作为该方法的一个应用，我们得到了高斯密度分布在双散射近似下相干强度的解析表达式。特别地，我们量化了相干后向散射和前向散射的贡献。
