本文从几个简单的模型出发，解释了多原子系统超辐射--合作自发辐射的一般性质。首先，我们考虑两个原子的自发辐射，它们之间的距离小于波长。然后描述了小体积内N原子系统的超辐射动力学。我们的主要注意力放在超辐射光子统计。给出了超辐射脉冲的主要部分的泊松统计量，并论证了超辐射脉冲成为亚泊松统计量的特殊条件。
General properties of super-radiance--cooperative spontaneous emission of multi-atomic systems are explained on the basis of some simple models. First we consider spontaneous emission of two atoms separated from each other by a distance less than the wavelength. Then the kinetics of super-radiance of N-atomic system in a small volume are described. The main attention we put into super-radiance photon statistics. We show the Poissonian statistics for the main part of super-radiance pulse and demonstrate the special conditions when it can be Sub-Poissonian one.
