The problem of solving light was installed about thirty years ago and was widely considered in different approximations. In this paper, this process is investigated using both perturbation theory and numerical integration of the system of Liouville–Maxwell differential equations.
Keywords: coherent excitation, density matrix, Liouville equation.
