Theoretical description of high-order harmonic generation in solids
We consider several aspects of high-order harmonic generation in solids: the effects of elastic and inelastic scattering, varying pulse characteristics and inclusion of material-specific parameters through a realistic band structure. We reproduce many observed characteristics of high harmonic generation experiments in solids including the formation of only odd harmonics in inversion-symmetric m...
متن کاملStrong-field perspective on high-harmonic radiation from bulk solids.
Mechanisms of high-harmonic generation from crystals are described by treating the electric field of a laser as a quasistatic strong field. Under the quasistatic electric field, electrons in periodic potentials form dressed states, known as Wannier-Stark states. The energy differences between the dressed states determine the frequencies of the radiation. The radiation yield is determined by the...
متن کاملMultislit interference patterns in high-order harmonic generation in C60
We study high-order harmonic generation in C60 molecules interacting with a linearly polarized intense short laser pulse at nearand mid-infrared wavelengths, using an extension of the so-called three-step or Lewenstein model to the molecular case. The results exhibit modulations in the plateaus of the spectra at the longer wavelengths, which are present for ensembles of aligned as well as rando...
متن کاملHigh-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...
متن کاملHigh-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...
