TL;DR: This work demonstrates Autler-Townes (AT) splitting of four-wave mixing in an electromagnetically induced transparency window, which results from the destructive interference between a three-photon process and a five- photon process.
Abstract: We demonstrate Autler–Townes (AT) splitting of four-wave mixing in an electromagnetically induced transparency window, which results from the destructive interference between a three-photon process and a five-photon process. The primary and secondary AT splittings are achieved via induced atomic coherence in a four-level Y-type atomic system. Theoretical calculations fit well with the experimentally measured results. Such controlled multichannel splitting of nonlinear optical signals can have potential applications in optical communication and quantum information processing.

TL;DR: In this paper, a simple description of FWM in terms of frequency-modulation-induced sidebands is discussed, and population pulsations of the inverted carrier system due to nonlinear beat frequency inversion modulation are identified as the microscopic origin.
Abstract: Studies on high-efficiency four-wave mixing (FWM) in semiconductor lasers up to detuning frequencies of about 21 GHz are discussed. Population pulsations of the inverted carrier system due to nonlinear beat frequency inversion modulation are identified as the microscopic origin. A simple description of FWM in terms of frequency-modulation-induced sidebands is discussed. >

TL;DR: In this paper, the effects of finite pump beam correlation length in four-wave mixing processes were investigated. But the model was not applied to the case of a KrF laser-pumped methane Raman amplifier.
Abstract: Intensity averaging of pump beams in a Raman amplifier can be treated using a four-wave mixing model. The model shows explicitly the consequences of finite pump beam correlation length in four-wave mixing processes. Phase conjugate effects in a Raman amplitier are observed and described. Measurements of four-wave mixing effects in a KrF laser-pumped methane Raman amplifier agree with the model.

TL;DR: In this paper, the authors theoretically investigate the dually dressed electromagnetically induced transparency, and the multidressed four-wave mixing (FWM) and six-wave blending (SWM) processes in an inverted-$Y$-type atomic system with Zeeman sublevels.
Abstract: We theoretically investigate the dually dressed electromagnetically induced transparency, and the multidressed four-wave mixing (FWM) and six-wave mixing (SWM) processes in an inverted-$Y$-type atomic system with Zeeman sublevels. The results show that the Zeeman degeneracy of the dark states can be lifted by the dressing field as its intensity is increased. Moreover, the derived analytical expressions indicate that one can, for example, selectively create secondary dark states on the multi-Zeeman-sublevel dark states (by tuning the coupling field), distinguish two different types of dark states generated in two FWM processes (by properly controlling the coupling field intensity), and selectively enhance multi-FWM signals coming from various paths consisting of split Zeeman sublevels (by tuning the dressing field). The SWM signals can be either enhanced or suppressed by controlling the dressing field.
