STUDY OF ADDITIONAL RESONANCES IN FREQUENCY SPACE AND PERMANENT DIPOLE-MOMENT EFFECTS ON NONDEGENERATE 4-WAVE-MIXING SIGNALS

The characteristics of the resonances emerging as a consequence of inc orporating a permanent dipole moment in the non-degenerate four-wave m ixing technique, are investigated in the framework of a local homogene ous-linewidth third-order perturbation model. Results show that the ef fects of the permanent dipole moments on the nonlinear signal topology are a consequence of neglecting the rotating-wave approximation.
