| 摘 要： | 从理论上解释了利用相位调制光场如何实现多光子跃迁的量子相干控制。在弱场作用下研究了几种整形激光脉冲形式与二能级原子系统的相互作用过程,研究了整形激光脉冲作用下双光子过程中的量子衍射效应。利用微扰理论给出了多光子跃迁过程的解析表示,根据解析表示解释了阶跃相位和余弦相位调制光场作用下多光子跃迁几率的量子相干控制。结果表明,这两种相干控制过程中都有跃迁几率消除现象,而且不同调制相位光场的作用结果对应着不同的几率消除位置。

| Abstract: | We theoretically explain how to achive the quantum coherent control of multi-photon transition by phase-modulated lightfield.The interaction between several types of shaped laser pulse and a two-level system is studied within the weak field regime.Quantum diffraction effect during the two-photon transition affected by a shaped laser pulse is studied.Under the perturbation theory,the analytical solutions of multi-photon transition probabilities are obtained.Based on these analytical expressions,we demonstrat... |
