| 摘 要： | 研究了置于光腔中的两个二能级原子，在强相干场驱动下的共振荧光光场的辐射场相干性质，发现在坏腔条件下，可以通过调节光腔与相干场的频率来提高一阶可见度和减小二阶关联函数.这是因为改变光腔与相干场的频率会引起原子修饰态布居数的改变，导致一阶可见度和二阶关联函数发生显著变化.关键词：光腔两个二能级原子一阶可见度二阶关联函数

| Abstract: | We have investigated the coherence of resonance fluorescence for a coherently driven two two-level atoms coupled to a single-mode cavity in the bad cavity limit. By adjusting the detuning of the cavity-mode frequency from the driving filed frequency, we can enhance the fringe contrast factor as well as decrease the second order correlation function. The surprising effect produced by the detuning has an effect on the atomic dress-state population, which makes the fringe contrast factor and the second order correlation function changed evidently. |
