摘要

在强场近似的框架外，我们从理论上研究了在排列的双原子分子系综中产生的激光辐射的高次谐波的光谱特征。这些研究是在Yukawa势的双中心推广所给出的模型框架内，基于数值计算进行的。基于对高次谐波光谱中多中心效应的分析，探讨了不同电子轨迹和离子核势的干扰对利用高时间分辨率非线性光谱提取分子核子系统状态光谱信息准确性的影响。

Coulomb and Quantum Interference Effects in the Spectra of High-Order Harmonics Generated by Aligned Molecules

We study theoretically the features of the spectra of high-order harmonics of laser radiation generated in an ensemble of aligned diatomic molecules outside the framework of the strong-field approximation. The studies were carried out on the basis of numerical calculations within the framework of a model given by a two-center generalization of the Yukawa potential. Influence of the interference of contributions from different electron trajectories and the ion core potential on the accuracy of extracting spectroscopic information about the state of the nuclear subsystem of a molecule using high temporal resolution nonlinear spectroscopy based on the analysis of multicenter effects in the spectra of high-order harmonics has been explored.
