We have considered the stimulated one-photon spectra for a system consisting of two identical three-level atoms interacting simultaneously with a strong pump field and a weak signal field. The atoms consist of an upper excited state and two lower states and they interact through their...

We have studied stimulated three-photon processes arising from the interaction of a system of two-identical three-level atoms with a strong pump field and a weak signal field simultaneously. The atoms consist of an upper excited state and two lower states and they interact through their...

The two-photon resonance fluorescence spectrum of a three-level atom is shown to consist of the low frequency modes in addition to the high frequency ones in the limit of high photon densities. The spectral function for the low frequency modes consists of two lorentzian lines describing: the...

A theory is developed concerning the excitation spectrum arising from the interaction between two-identical three-level atoms (molecules), one of which is excited in the presence of a strong resonant electromagnetic field (pump field). General expressions for the Green's functions are derived in...

The excitation spectrum of two identical three-level atoms is considered when a strong electromagnetic field operates resonantly between two levels of the atoms. While undergoing the transition into the excited state, the atoms interact through their dipole-dipole interaction and radiate to each...

The excitation spectrum arising from photon density-density correlations has been calculated for two types of a single three-level atom for which electronic transitions occur: from two different upper levels to a common lower one and from a common upper level to two different lower levels,...

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...

Numerical calculations are presented for the excitation spectrum of two identical three-level atoms interacting with a strong resonant laser field. The atoms interact through their dipole-dipole interaction and radiate to each other as well. The spectrum of the symmetric and antisymmetric modes...
