| Abstract: | Two-photon resonant nondegenerate four-wave mixing (NFWM) with theaddition of a coupling field in Ba atomic vapour has been studied. Wefind that coherence of the atomic level transitions leads tosuppression of the NFWM signal, giving rise to a dip with a linewidththat is linearly proportional to the intensity of the coupling field. |
| Keywords: | nondegenerate four-wave mixing electromagnetically induced transparency |
