非共振和/或强laser场驱动下二能级量子系统的半经典缀饰态

Semiclassical dressed states of two-level quantum systems driven by nonresonant and/or strong laser fields

摘要:

本文给出了在非共振和强激光场驱动下的相干态二能级量子系统的半经典缀饰态和相应的准能量的解析表达式。这些表达式在适当的微扰展开中是一阶的,并且已经包含了这些系统在这种特定条件下所显示的动力学和光谱特性的所有相关物理信息。激光场参数对跃迁频率、选择规则和谱线强度的影响可以通过准能级图和不同半经典修饰态之间的允许跃迁来容易地理解。

英文摘要:

Analytical expressions for the semiclassical dressed states and corresponding quasienergies are obtained for a two-level quantum system driven by a nonresonant and/or strong laser field in a coherent state. These expressions are of first order in a proper perturbative expansion, and already contain all the relevant physical information on the dynamical and spectroscopic properties displayed by these systems under such particular conditions. The influence of the laser field parameters on transition frequencies, selection rules, and line intensities can be easily understood in terms of the quasienergy-level diagram and the allowed transitions between the different semiclassical dressed states.
