A semiclassical analytic theory which describes the excitation of atomic Rydberg states by intense laser radiation is formulated in the multiphoton limit of ionization. The theory is based on the separation of the electron motion in fast oscillations in the laser field and slow scattering in the Coulomb field of the nucleus. It allows one to calculate classical cut-off positions in the distribution of excited atoms in principal and orbital quantum numbers, and to identify the effect of quantum interference.

多光子状态下原子的受抑电离

在电离的多光子极限中，提出了一个描述经典的Rydberg态通过强激光辐射激发的半经典分析理论。该理论基于电子运动在激光场中快速振荡和原子核库伦场中缓慢散射的分离。它使人们能够计算主量子和轨道量子数中激发原子分布的经典截止位置，并确定量子干扰的影响。
