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 。
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.
