Abstract We demonstrate experimental observation of vacuum Rabi splitting (VRS) of four-wave mixing and six-wave mixing in a collective five-level atomic-cavity coupling system. We study the control of VRS via changing the dressing effect of the vacuum cavity mode; i.e., the cavity mode dressing effect can selectively split the right or left peak when cavity-atom detuning and atom number N are changed. We further report that the cavity window and two electromagnetically induced transparency (EIT) windows induced by the dressing field interfere with each other because of different two-photon conditions they satisfy. Additionally, we investigate the self-dressing field effect on VRS of six-wave mixing (SWM) inside the cavity. Such investigation results can find application in all-optical switches and optical communications.
