Estimating the plasmonic field enhancement using high-order harmonic generation: The role of inhomogeneity of the fields
T. Shaaran, M. F. Ciappina, M. Lewenstein
In strong field laser physics it is a common practice to use the high-order harmonic cutoff to estimate the laser intensity of the pulse that generates the harmonic radiation. Base…

Tailoring high-order harmonic generation with nonhomogeneous fields and electron confinement
M. F. Ciappina, Srdjan S. Acimovic, T. Shaaran +3
We study high-order harmonic generation (HHG) resulting from the illumination of plasmonic nanostructures with a short laser pulse. We show that both the inhomogeneities of the loc…
