Abstract : The affect of the coherent dipole-dipole interactions on the resonance fluorescence spectra of two, two-level atoms, driven by coherent external field, has been investigated. The explicit dependence of the coherent dipole-dipole interactions on the distance between the treatment of the spectra. For the case of two, two-level atoms with a fixed distance smaller than a wavelength an analytical result for the resonance fluorescence line shape has been obtained and the result has been compared with previous works. The Langevin Equations for Intrinsic Bistability, the effects of the Langevin noise terms on intrinsic bistability are analyzed for the case in which dephasing constant is large relative to that of the relaxation. Within this approximation one dimensional Ito differential equation for the inversion of population has been developed. The tunneling process and the passage times between the two stable states in the intrinsic bistability are studied.
