研究了高Qkerr介质腔中的二能级原子与双模光场相互作用系统中 ,光场的相位自调制效应对原子布居的影响 .研究发现随着相位自调制强度的增加 ,原子与光场的耦合减弱 ,并证明光场相位自调制强度与光场的各模有关 .

The influence of the strength of phase self-modulation of light field on the atomic population is studied in the system consisting of a two-level atom interacting with two-mode light field in a high-Q cavity surrounded by Kerr medium. The study shows atom-field coupling becomes weak when the strength of phase self-modulation increases and it proved that the strength of phase self-modulation is related to respective mode of light field. At the same time, relation between the atomic population and photon number is investigated.
