Correlation effects in high-order harmonic generation from finite systems

High-Order Harmonic Generation from Molecules

Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. High harmonic generation in atoms is well understood in terms of the three step model (ionization, propagation and recombination), and much attention has been payed to the dynamics of t...

Intensity-dependent atomic-phase effects in high-order harmonic generation.

The far-field angular distributions of high-order harmonics of a 1054-nm laser, with orders ranging from the lower teens to the upper thirties, have been measured in thin, low-density Ar, Kr, and Xe targets. The 1.25times-diffraction-limited, 1.4-ps-duration, Gaussian laser pulses were focused to intensities ranging from 3 X 10' to 3 X 10' W/cm, using f/70 optics. A gas target localized the gas...

High-order harmonic generation from ions in a capillary discharge.

We demonstrate a significant extension of the high-order harmonic cutoff by using a fully-ionized capillary discharge plasma as the generation medium. The preionized plasma dramatically reduces ionization-induced defocusing and energy loss of the driving laser due to ionization. This allows for significantly higher photon energies, up to 150 eV, to be generated from xenon ions, compared with th...
