摘要
研究了光场与级联型三能级原子依赖强度耦合系统中光子的反聚束特性.研究发现随着平均光子数n-值、原子-光场耦合系数g值的增大,光子由表现明显的反聚束效应和聚束效应交替变换状态逐渐转到表现聚束效应状态.该系统中平均光子数n-较原子-光场耦合系数g对光子的反聚束效应的影响更大.
The photon anti-bunching effects in the intensity-dependent coupling interaction between a three-level cascade atom and a light field are studied by numerical calculation. With the increasing of the values of n and g,the character of photons varies from alternation between antibunching effect and bunching to hunching only. n plays a more important role than g in photon antibunching effects.
