An analysis is made of the influence of an electric dipole–dipole interaction of resonant centers on the self-induced transparency of two-level solid media. The conditions under which this interaction is the main mechanism of decay of optical solitons are identified. It is shown that the main contribution to the decay process comes from pairs of closely spaced centers. In the case of such pairs the distance between the centers is much less than the average. Differential equations describing the change in the soliton duration are derived.

The intrinsic optical bistability, soliton formation, and transient phenomena such as the free polarization decay and photon echo in dense resonant media are investigated, taking into account the short-range dipole-dipole interaction of atoms.

We investigate local-field effects in nonlinear optical materials composed of two species of atoms. One species of atom is assumed to be near resonance with an applied field and is modeled as a two-level system while the other species of atom is assumed to be in the linear regime. If the near dipole-dipole interaction between two-level atoms is negligible, the usual local-field enhancement of the field is obtained. For the case in which near-dipole-dipole interactions are significant due to a high density of two-level atoms, local-field effects associated with the presence of a optically linear material component lead to local-field enhancement of the near dipole-dipole interaction, intrinsic cooperative decays, and coherence exchange processes.
