TLDR
In this article, high-order harmonic generation for molecules in linearly polarized laser pulses by numerical solution of the Schr\"odinger equation was studied and maxima and minima due to intramolecular interference were found in the dependence of the harmonic intensities on the internuclear distance and on the orientation of the molecules.Abstract:
We study high-order harmonic generation for ${\mathrm{H}}_{2}^{+}$ and ${\mathrm{H}}_{2}$ model molecules in linearly polarized laser pulses by numerical solution of the Schr\"odinger equation. Maxima and minima due to intramolecular interference are found in the dependence of the harmonic intensities on the internuclear distance and on the orientation of the molecules. These extrema can be approximately predicted by regarding them as the result of interference between two radiating point sources located at the positions of the nuclei.read more

Laser induced molecular axis alignment: measurement andapplications in attosecond science
TL;DR: In this paper, the authors report the measurement and applications of molecular axis alignment induced by strong non-resonant linearly polarised laser fields, which overcomes the loss of information that results from averaging angle-dependent quantities over all the possible orientations of an isotropic sample.

Accurate prediction of interference minima in linear molecular harmonic spectra by a modified two-center model*
TL;DR: In this article, a modified two-center model was proposed to predict the harmonic minimum positions consistent with those simulated by strong field approximation (SFA), and the locations of the harmonic minima are related to the nuclear distance between the two main atoms contributing to the harmonic generation.

Molecular high-order harmonic spectra and its application to the generation of the isolated attosecond pulse
TL;DR: Results show that the 7th harmonic order is enhanced with the nuclei around the equilibrium internuclear, and as the internuclear distance increased, this enhanced harmonic produces a red-shift (even disappearance).

Self-probing of Molecules with High Harmonic Generation
TL;DR: In this article, the most important aspects of the molecular self-probing paradigm are presented, which views the process of high harmonic generation as "a molecule being probed by one of its own electrons".
