摘　　要：主要研究Y型四能级原子系统中缀饰场功率控制的级联双缀饰四波混频的缀饰相互作用。首先,基于缀饰态理论求解当两个缀饰场同时入射非线性光学介质时的缀饰态的本征值,研究缀饰能级的位置与缀饰场功率的关系。接着,使用改变缀饰场功率,扫描探测场失谐的方法,研究四波混频的缀饰相互作用。研究发现,当两个缀饰场的失谐不同时,原子介质中会产生三个缀饰能级,相同时则会产生两个缀饰能级;而且两个缀饰场功率的变化都会令缀饰能级的位置发生偏移,偏移的程度决定于缀饰场的失谐。The power control of the interaction of dressing fields of sequential-doubly-dressed four-wave mixing(FWM)in Y-type four energy-level systems is studied in this paper.Firstly,the eigenvalues of the dressed states are solved when two dressing fields are incident simultaneously in the nonlinear optical media based on the theory of the dressed states.And the relation of the position of the dressed states and the power of the dressing fields is researched.Then,the interaction of two dressing fields of FWM is shown by scanning the frequency detuning of the probe field along with changing the power of the dressing field.It is found that three embellishment energy levels are produced in the atomic medium when the detuning of the two embellishment fields are different,and when they are the same,two embellishment energy levels are produced.Moreover,changes in the power of the two embellishment fields cause the position of the embellishment energy levels to be shifted,and the degree of the shift is determined by the detuning of the embellishment fields.
