摘　　要：文章分析了Λ-型三能级原子与腔耦合系统在强耦合条件下,腔透射谱在随腔模失谐的变化情况。结果表明,改变腔模失谐不但对正交劈裂峰会产生频移,同时对内腔EIT峰也会产生频率推移,并且在单光子失谐时,推移程度也有所不同;当腔模失谐达到自由光谱区的一半时,内腔暗态极子模出现双峰结构。这一结果对研究基于原子腔系统的关联光场具有积极的意义。In this paper, the cavity transmission spectrum which changed with the cavity mode detuning was studied under conditions of strong coupling in the A-type three-level atom-cavity coupling system. The research showed that the cavity mode detuning not only makes the frequency of normal splitting peaks shift, but also pushes the frequency of EIT peaks, and the degree of pushed are different in different single photon detuning. The EIT mode showed the double-peaks when the cavity mode detuning reached half of the free spectral range. The result has the positive meaning for the research of correlated light based on the cavity -- atom system.
