  • 利用已得到的原子约化密度算符主方程,研究了两能级原子与宽带压缩真空态光场的双光子相互作用.通过求解双光子Bloch方程,利用量子回归定理,得到双光子荧光的二阶关联函数.在此基础上讨论了原子的双光子荧光的反聚束效应.
    By using the two photon Bloch equation and quantum regression theorem, the second order correlation function of two photon fluorescence of a two level atom in a broad band squeezed vacuum is obtained. From this, the bunching and the antibunching effects of two photon fluorescence are investigated. We find that the second order correlation function is dependent on the squeezing parameter (|M|) of the squeezed vacuum. There is a critical value (Γ/4g) for |M|,above which the second order correlation function oscillates around 1. This indicates that the two photon fluorescence can exhibit both antibunching and bunching effects. Below the critical value, the second order correlation function does not oscillate and the two photon fluorescence exhibits the antibunching effect only.
