摘　　要：Polarization dependence of the enhancement and suppression of four-wave mixing （FWM） in a multi- Zeeman level atomic system is investigated both theoretically and experimentally. A dressing field applied to the adjacent transition can cause energy level splitting. Therefore, it can control the enhancement and suppression of the FWM processes in the system due to the effect of electromagnetically induced transparency. The results show that the pumping beams with different polarizations select the transitions between different Zeeman levels that, in turn, affect the enhancement and suppression efficiencies of FWM.Polarization dependence of the enhancement and suppression of four-wave mixing （FWM） in a multi- Zeeman level atomic system is investigated both theoretically and experimentally.
