“…Recently, we have observed Autler-Townes (AT) splitting of the four-wave mixing (FWM) signals with dressing effects [25,26] generated in a multilevel atomic system. We have also observed the evolution of the enhancement (bright state) and suppression (dark state) in FWM processes by controlling the frequency detuning of the additional laser field [27,28]. Considering the origin of VRS and OB, and the application of the dark state in the MWM process, we deduce that dark and bright states can affect the properties of VRS and OB behavior in our proposed atom-cavity system and make that the focus of our research.…”

We theoretically demonstrate the influence of dark and bright states on vacuum Rabi splitting (VRS) and optical bistability (OB) of the multi-wave-mixing (MWM) process in a collective four-level atomic-cavity coupling system. We numerically investigate the multidressed VRS and OB behavior of the zero-and high-order transmitted cavity modes of MWM signals. A further study demonstrates that VRS and self-Kerr nonlinearity OB can coexist and compete with each other in a cascade relationship, based on which we achieve the goal to control VRS and OB simultaneously through the dark state in the atomic system.

We investigate fluorescence (FL) and spontaneous parametric four-wave mixing (SP-FWM) signals in V-, Λ- and N-type energy level systems by changing the frequency detuning or power of the dressing field in Pr3+ doped Y2SiO5 at 77 K. The lifetime of the two kinds of signals has been calculated, and the desired experimental results have been obtained. We successfully control the intensity and lifetime of fluorescence and SP-FWM signals by changing the power or frequency detuning of the dressing field. The research has potential applications in optical switches and all optical communication.

“…These feasibilities and adjustability are discussed in each section for each atomic scheme under the investigation. Although we are interested in the experiment on the wave mixing in the context of spontaneous emission study, there are many other recently reported works [31][32][33][34][35][36] related to this subject may be interesting for future studies of Autler-Townes multiplet spectroscopy.…”

We extend the concepts of the Autler-Townes doublet and triplet spectroscopy to quartuplet, quintuplet and suggest linkages in sodium atom in which to display these spectra. We explore the involved fundamental processes of quantum interference of the corresponding spectroscopy by examining the Laplace transform of the corresponding state-vector subjected to steady coherent illumination in the rotating wave approximation and Weisskopf-Wigner treatment of spontaneous emission as a simplest probability loss. In the quartuplet, four fields interact appropriately and resonantly with the five-level atom. The spectral profile of the single decaying level, upon interaction with three other levels, splits into four destructively interfering dressed states generating three dark lines in the spectrum. These dark lines divide the spectrum into four spectral components (bright lines) whose widths are effectively controlled by the relative strength of the laser fields and the relative width of the single decaying level. We also extend the idea to the higher-ordered multiplet spectroscopy by increasing the number of energy levels of the atomic system, the number of laser fields to couple with the required states. The apparent disadvantage of these schemes is the successive increase in the number of laser fields required for the strongly interactive atomic states in the complex atomic systems. However, these complexities are naturally inherited and are the beauties of these atomic systems. They provide the foundations for the basic mechanisms of the quantum interference involved in the higher-ordered multiplet spectroscopy.
