Competition among four-wave mixing with two dressing fields, the six-wave mixing with one dressing field as well as the eight-wave mixing propagating along the same direction can be evoked by adjusting laser beams because these multi-wave mixing signals are induced by atomic coherence between common levels.

研究发现，通过调节激光束方向，沿同一方向出射的八波混频、双缀饰四波混频和单缀饰六波混频信号因共用能级的原子相干产生而出现竞争现象，通过控制缀饰场减弱四波混频和六波混频信号强度，可以达到增强八波混频信号的目的。
