Abstract
Superradiance is an effect of the cooperative decay of multiatomic systems. It is usually supposed that the superradiance takes place in the case of the open (resonatorless) systems. However, as it was shown recently,1−3 the cooperative processes could affect essentially on the radiative decay of an ensemble of atoms placed into the optical cavity. The superradiance in an optical cavity is really a new type of the radiative decay, which is characterized by the number of the specific features. For example, the peak intensity and the temporal width of the pulse depend essentially on the cavity q-factor, and using these dependencies we can effectively control by the pulse shape. Varying the cavity q-factor and the initial conditions we can optimize the process of the radiative decay in respect with its rate.121 The effect of the optimal decay is due to the symmetric properties of the atomic-field system, and such decay was called by a collective superradiance.[2]
