FIG. 1.

(a) The diagram of relevant Na energy levels. (b) The scheme of the experiment. Inset gives the spatial alignments of the incident beams. (c) and (d) The dressed-state pictures of the suppression and enhancement of FWM for the two-level system, respectively. (e) The dressed-state picture of the suppression of FWM for the ladder system.

The evolution of the dressed effects for different values: (a) (squares), −84.3 GHz (circles), −67 GHz (triangles), 71.3 GHz (reverse triangles), 88.6 GHz (pentagons), and 105 GHz (hexagons) from right to left. Inset: theoretical plots using experimental parameters. (b) (squares), −2.6 GHz (triangles) and −13 GHz (circles). (c) (squares), 38 GHz (triangles) and 42.2 GHz (circles).

(a) Measured enhanced DFWM signal spectra for different coupling field intensities, (squares), , (circles) and (triangles). Inset: the experimental data and theoretical curve of the power dependence of the enhanced FWM signal, . (b) Measured suppressed DFWM signal spectra for different coupling field intensities, (squares), , (circles) and (triangles). Inset: the experimental data and theoretical curve of the power dependence of the suppressed FWM signal, .

Mutual suppression between the DFWM signal and the NDFWM signal . (a) Upper curves: pure-DFWM signal (squares), singly dressed DFWM signal (triangles), doubly dressed DFWM (circles). Lower curves: pure-NDFWM signal (squares), singly dressed NDFWM signal (triangles), and doubly dressed NDFWM signal (circles), . (b) Interplays between (b1) DFWM and (b2) NDFWM processes. The conditions are the same as in (a), .
