“…Our goal is to illustrate the dependence of the absorption/gain of the radiation fields on their intensities and the relaxation rates both radiational and collisional. We shall follow the standard procedure in the density matrix Liouville-von Neumann equation, in which we take into account its entire multipole component that is accessible to the D 1 configuration [14]. This approach is favourable as the selective addressing of higher rank atomic polarization multipole moments is possible, as has been shown in [15].…”

We analyse the three-colour electromagnetically induced transparency for the D 1 transition in cold 87 Rb atoms. We report an enhancement of the electromagnetically induced emission of a drive field as an exclusive enhancement of the third-and fourth-rank components of the density matrix. Moreover, the gain experienced by the drive field is attributed to the influence of the quantum switching effect on the increased absorption of the probe field. The electromagnetically induced emission effect is employed to generate slow light Gaussian-wave trains with shape preserving. These soliton trains were not only generated in the drive channel as has been designated but also in the switch channel which reveals multiple-light storage phenomenon.

“…Moreover, in most cases we add with some delay the second coupling pulse so that the restoring of the probe pulse can be checked. According to the standard procedure, we shall describe the dressed atom state using the density matrix Liouville-von Neumann equations as in [20]. However, these equations will be modified to account for the two-colour excitation by the coupling and probe beams in the similar manner to that used in the paper of Zhu [22].…”
