High order harmonic generation in noble gases using plasmonic field enhancement
M. F. Ciappina, T. Shaaran, M. Lewenstein
We present theoretical studies of high-order harmonic generation (HHG) in rare gases driven by plasmonic field enhancement. This kind of fields appears when plasmonic nanostructure…
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…
Above threshold ionization by few-cycle spatially inhomogeneous fields
M. F. Ciappina, J. A. Pérez-Hernández, T. Shaaran +3
We present theoretical studies of above threshold ionization (ATI) produced by spatially inhomogeneous fields. This kind of field appears as a result of the illumination of plasmon…
Quantum-orbit analysis of high-order harmonic generation by resonant plasmon field enhancement
T. Shaaran, M. F. Ciappina, M. Lewenstein
We perform a detailed analysis of high-order harmonic generation (HHG) in atoms within the strong field approximation (SFA) by considering spatially inhomogeneous monochromatic las…
Time-delayed nonsequential double ionization with few-cycle laser pulses: importance of the carrier-envelope phase
C. Figueira de Morisson Faria, T. Shaaran, M. T. Nygren
We perform theoretical investigations of laser-induced nonsequential double ionization with few cycle pulses, with particular emphasis on the dependence of the electron-momentum di…
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…
