Na_2中由一对耦合能级相干叠加导致的双光子吸收的干涉增强效应

Interference enhancement of two-photon absorption caused by a pair of coherent superposition levels in Na_2

在中间共振增强能级是一对波函数叠加的耦合能级的钠分子菱形四能级系统中 ,实验观察了由该两耦合能级的相干叠加作用所导致的不等频双光子吸收的干涉增强效应 ,并运用密度矩阵方程对这一实验现象进行了计算 ,其结果与实验符合得很好 .

In the sodium dimer rhomb-type four-level system with a pair of coherent superposition levels, the interference enhancement of two-photon absorption caused by coherent superposition of the coupling levels is experimentally observed. The calculated results using density matrix equation are in good agreement with the experimental results.
