THE EFFECTS OF TRANSVERSE RELAXATION AND OPTICAL PUMPING ON THE RESONANCE FLUORESCENCE

Although the resonance fluorescence spectrum of coherent light scattering from a two-level atom has been discussed in many papers, the effects of longitudinal, transverse relaxation and optical pumping have not yet been considered simultaneously in the motion equations. By solving the optical Bloch equations including the longitudinal relaxation time T₁, transverse relaxation time T₂ and optical pumping parameter Δ₀, in the case T₂/T₁«1, we obtain the spectrum with dip in the central peak besides the familiar spectrum of three peaks. In addition, we find that the parameter Δ₀ and detuning Δ_ω have influence on the symmetry, height and width of the spectrum of the three peaks.
