Impact of Increasing the Detuning on The Nonlinear Electric Susceptibility in N-type Four Levels atom

Abstract

     The effect of increasing Rabi frequencies of laser beams in resonance with the frequency of the allowed transitions on the nonlinear electric susceptibility has been studied both with or without considering the detuning in N type four levels atoms response to the laser beams. The impact of the increasing the Rabi frequencies of laser beams with increasing the detuning of the transitions on the electric susceptibility shows a reduction in the nonlinear electric susceptibility.
