Abstract

We propose a scheme to study coherent control of the atomic Talbot effect using an N-type four-level atomic system in the Raman regime. We show that the intensity of the atomic Talbot image can be efficiently manipulated using Rabi frequency of the control field. However, this manipulation strongly depends on the proper choice of Raman and control field detunings. In particular, the sign of control field detuning leads to two distinct features. In one case, the intensity increases up to a maximum as a function of the control field, followed by a decreasing trend, while in other case, we find only a monotonically decreasing trend.
