The influence of a second resonance on the saturation characteristics of the four-wave sum mixing

E. Koudoumas, Thomas Efthimiopoulos

Experimental results are presented, related to the saturation mechanisms of the four-wave sum mixing (4-WSM) generation in Hg when a double resonance enhancement is employed, that is, a two photon resonance to the /spl delta//sup 1/S/sub 0/ state followed by the /spl delta//sup 1/S/sub 0/-6p'/sup 3/D/sub 1/ one photon coupling. This coupling is shown to alter the saturation characteristics of the four-wave sum mixing radiation by affecting the two-photon excitation to the /spl delta//sup 1/S/sub 0/ state, reduce the ionization of the Hg atoms by the incoming radiation and create an absorption window for the generated radiation in a region near the autoionizing state by modifying the linear susceptibility.>

Level splitting effects in CW resonant four-wave mixing

Sergei A Babin, S.I. Kalukov, U. Hinze +2 more

Summary form only given. Various schemes of resonant frequency conversion using four-wave mixing (FWM) have been investigated recently. For example, sum-frequency FWM in Hg atoms has been used for generation of CW radiation at 121.56 nm, corresponding to the Lyman-/spl alpha/ line of hydrogen and efficient difference frequency mixing has been demonstrated in double-/spl Lambda/ level configurations of Na/sub 2/ molecules. We present novel investigations on the resonance structure of the FWM-spectra in the case of up-conversion in a double-/spl Lambda/ scheme realized in Na/sub 2/.
