The influence of a repump laser on a nearly degenerate four-wave-mixing (ND-FWM) spectrum was investigated. We found the amplitude and the line shape of the NDFWM depended strongly on the detuning of the repump field. A five-peak structure was observed, and at some certain repump detuning a dip appeared at the central peak. A rough analysis was proposed to explain this effect.
