摘　　要：提出了一种利用简并V型三能级原子与振幅很大的单模相干光场的远离共振相互作用 ,制备四光子相干态的有效新方案 同时证明了在相同的条件下 ,按照相同的方法不能制备出四成分以上的相干态的叠加态 ,即当在腔中注入的第三个原子的速度与第二个原子的速度相等时 。A new scheme of generating the four-photon coherent states is presented through interaction of a degenerate V-type three-level atom with single-mode coherent state cavity field of large amplitude under far-off resonant condition. It is impossible to generate the coherent states with more than four-component by the same method mentioned above. That is, the four-photon coherent states remain unchanged in the cavity when the third atom with the same velocity as the second atom is injected into the cavity.
