摘要
We experimentally investigate the interplay between two coexisting six-wave mixing(SWM)signals and the interference between coexisting four-wave mixing(FWM)and SWM signals in a five-level atomic system of85 Rb.When two electromagnetically induced transparency windows gradually overlap in frequency,the competition between these two SWM signals arises.Moreover,we report the experimental result which shows that the temporal interference with femtosecond time scales between FWM and SWM signals.
