Abstract: Numerical calculations are presented for the two-atom Hanle-type resonance spectra arising from the interaction of two identical three-level atoms with a strong electromagnetic field whose frequency mode is highly populated. The two-atoms interact through their dipole-dipole interaction and radiate to each other as well. The spectral functions describing the excitation spectra of the symmetric and antisymmetric modes have been computed for selected values of the parameters involved. The computed spectra are graphically presented and discussed. The intensities of a number of peaks are found to change from positive to negative values, and vice versa, depending upon the values of the parameters describing the system. The dipole-dipole interaction between the atoms is found to have a pronounced effect in determining the spectra of the antisymmetric modes of the system and, in particular, it enhances the physical process of optical amplification of the signal field.
