The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Attosecond science is based on electron dynamics driven by a strong optical electric field
and has evolved beyond its original scope in gas-phase atomic and molecular physics to …

The generation of ultrashort electron wavepackets is crucial for the development of ultrafast
electron microscopes. Recent studies on Coulomb-correlated few-electron number states …

Strong-field laser-matter interactions in nanoscale targets offer unique avenues for the
generation and detailed characterization of matter under extreme conditions. Field-driven …

Different from the high-order harmonic generation (HHG) from gases, we find that the yield of
HHG from solids exhibits unexpected modulations as a function of the driving laser intensity …

We investigate the process of phase-controlled high-order above-threshold photoemission
from metallic nanotips under bichromatic laser fields. Experimental photoelectron spectra …

Spectroscopic photoemission microscopy is used to detect and quantify a ponderomotive
shift in the energy of electrons that are emitted from a surface plasmon polariton focus. The …

In strong-field laser-matter interactions, energetic electrons can be created by
photoemission and a subsequent rescattering and can attain energy as much as 10 times …

We have investigated emission patterns and energy spectra of electrons from a tungsten
nanotip induced by circularly polarized femtosecond laser pulses. Variations of emission …
