The quantum dynamics of a V-type three-level system, whose two resonances are first excited by a weak probe pulse and subsequently modified by another strong one, is studied. The quantum dynamics of the multi-level system is closely related to the absorption spectrum of the transmitted probe pulse and its modification manifests itself as a modulation of the absorption line shape. Applying the dipole-control model, the modulation induced by the second strong pulse to the system's dynamics is quantified by eight intensity-dependent parameters, describing the self and inter-state contributions. The present study opens the route to control the quantum dynamics of multi-level systems and to quantify the quantum-control process.
研究了由弱探测脉冲首先激发两个共振，然后由另一个强脉冲修改的 V 型三能级系统的量子动力学。多能级系统的量子动力学与透射探测脉冲的吸收光谱密切相关，其修饰表现为吸收线形状的调制。应用偶极子控制模型，通过第二个强脉冲对系统动力学的调制由八个强度相关参数来量化，这些参数描述了自和状态间的贡献。本研究为控制多能级系统的量子动力学和量化量子控制过程开辟了道路。
