| 摘 要： | 研究了双模压缩真空场与Λ型三能级原子非共振相互作用系统中,场模失谐量对原子布居概率和光场的双模互关联函数、二阶相干度的影响.结果表明：失谐量使原子Rabi振荡呈现周期性崩塌与复苏现象；当光场初始压缩因子r较小时,失谐量将削弱光子的反聚束效应；当r较大时,失谐量又将增强光场两模相关的稳定性. |

| Abstract: | The influences of detuning on the atomic population, two-mode intensity correlation function and second-order correlation function in the system of two-mode squeezing vacuum field interacting non-resonantly with a Λ-type three-level atom are investigated. The results show that the collapse-and-revival of the atomic Rabi oscillation appears under the detuning. When the initial squeezed light-field factor r is weak, the detuning leads to the reduction of photon antibunching; while the factor r is strong, the detuning makes two-mode correlation properties steady. |
| Keywords: | Two-mode squeezing vacuum field Λ-type three-level atom Two-mode intensity correlation function Second-order correlation function |
