“…For example, Rayleigh-type nondegenerate FWM [4], which can be employed for the measurement of ultrafast longitudinal relaxation time in the frequency domain, has been demonstrated. We have also studied a new type of twophoton resonant FWM in a dressed atomic system [5]. This process provides a spectroscopic tool for measuring not only the resonant frequency and dephasing rate but also the transition dipole moment between two highly excited atomic states.…”

“…In this Letter we shall report for the first time a generalized scheme for resonant 2n-wave mixing in (n 1)-level systems with phase-conjugate geometry. Similar to the corresponding nondegenerate FWM technique we developed, the phase-matching conditions are not so stringent and can be achieved over a very wide frequency range from many hundreds to thousands of cm ÿ1 [4,5]. Moreover, due to the multiple resonance with the atomic transition frequencies, the 2n-wave mixing signal will be enhanced tremendously.…”

“…It exhibits a resonant line at a frequency corresponding to the transition from 6s6p 1 P 1 to 6s17d 1 D 2 . We then performed dressed-atom two-photon resonant FWM [5] in the 6s 21 S 0 -6s6p 1 P 1 -6s17d 1 D 2 cascade three-level system with a strong coupling field of frequency ! 3 driving the transition 6s17d 1 D 2 -6p 3=2 17d.…”

A generalized scheme for phase-conjugate resonant 2n-wave mixing, which has a high efficiency and is easy for phase matching, is proposed. As a new type of coherent laser spectroscopy this approach can be employed for studying highly excited atomic states or states with a high angular momentum. To demonstrate its feasibility we have studied the doubly excited autoionizing Rydberg states of Ba by phase-conjugate six-wave mixing, and have furthermore achieved eight-wave mixing in Na. This method may find wide application in related areas such as coherent transient spectroscopy, Autler-Townes spectroscopy and electromagnetically induced transparency. In particular, it may provide new insights into the nature of highly excited states.

“…Min Xiao et al [7] reported an experimental studying of generating highly efficient FWM and SWM processes simultaneously in an open-cycle Y-type atomic system, in which the dual-EIT windows are used to transmit the generated FWM and SWM signals, respectively. On the other hand, we have studied two-photon resonant four-wave mixing in a dressed atomic system [8] . This processes converts to a coherent superposition of signal from FWM and SWM in the weak coupling field limit.…”

We report a four-photon resonant nondegenerate eight-wave mixing (NEWM) in a dresses N-type six-level system. It has advantages that phase match condition is not stringent and NEWM signal is enhanced tremendously due to the multiple resonance with the atomic transition frequencies. In the prenence of a strong coupling field, the four-photon resonant NEWM spectrum exhibits Autler-Townes splitting. Compared to two-photon resonant nondegenerate four-wave mixing and three-photon resonant nondegenerate six-wave mixing in dressed atoms, four-photon resonant NEWM spectrum is more complicated and can provides information about the relaxation of higher-order atomic coherence.

The effects of Doppler broadening on Autler-Townes (AT) splitting in six-wave mixing (SWM) are investigated by the dressed-state model. We analyze the velocities at which the atoms are in resonance with the dressed states through Doppler frequency shifting and find that, depending on the wave-number ratio, there may be two resonant velocities which can originate from resonance with one of the dressed states or from resonance with two different dressed states. Based on this model, we discuss a novel type of AT doublet in the SWM spectrum, where macroscopic effects play an important role. Specifically, the existence of resonant peaks requires polarization interference between atoms of different velocities in addition to a change in the number of resonant atoms involved. Our model can also be employed to analyze electromagnetically induced transparency resonance and other types of Doppler-free high-resolution AT spectroscopy.
