We theoretically investigate the four-wave mixing (FWM) characteristics in a Ξ−V type atomic system. The generated FWM is obtained by utilizing the density matrix formalism and solving the master equation. Interesting discrimination in the number of emerged peaks due to the chosen laser scanning schemes was pointed out. The dressed state picture is employed to elucidate the number of peaks emerged as well as the peak positions in the spectra. The dependence of the generated FWM signal accordingly to the change of parameters, such as Rabi frequencies and frequency detunings of the applied fields, are presented and well explained in the simplified dressed state picture. A prominent increase in FWM intensity is obtained when the Rabi frequencies of the coupling and driving field are approximately equal. The frequency detuning of the applied fields causes the shift in the peak positions, peak shape, and even brings about the FWM intensity enhancement.
