Cluster size dependence of high-order harmonic generation [PDF]
New Journal of Physics, 2017 We investigate high-order harmonic generation (HHG) from noble gas clusters in a supersonic gas jet. To identify the contribution of harmonic generation from clusters versus that from gas monomers, we measure the high-order harmonic output over a broad ...

Femtosecond Single Cycle Pulses Enhanced the Efficiency of High Order Harmonic Generation [PDF]
Micromachines, 2021 High-order harmonic generation is a nonlinear process that converts the gained energy during light-matter interaction into high-frequency radiation, thus resulting in the generation of coherent attosecond pulses in the XUV and soft x-ray regions.

High-order harmonic generation from inhomogeneous fields [PDF]
Physical Review A, 2012 We present theoretical studies of high-order harmonic generation (HHG) produced by non-homogeneous fields as resulting from the illumination of plasmonic nanostructures with a short laser pulse. We show that both the inhomogeneity of the local fields and

Phase-matched high-order harmonic generation in pre-ionized noble gases [PDF]
Scientific Reports, 2022 One of the main difficulties of efficiently generating high-order harmonics in long neutral-gas targets is to reach the phase-matching conditions. The issue is that the medium cannot be sufficiently ionized by the driving laser due to plasma defocusing ...

Theoretical description of high-order harmonic generation in solids
New Journal of Physics, 2013 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.
