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 …

Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …

Attosecond science is based on steering electrons with the electric field of well controlled
femtosecond laser pulses. It has led to the generation of extreme-ultraviolet pulses with a …

The theoretical description and the experimental methods and results for above-threshold
ionization (ATI) by few-cycle pulses are reviewed. A pulse is referred to as a few-cycle pulse …

We report a source of free electron pulses based on a field emission tip irradiated by a low-
power femtosecond laser. The electron pulses are shorter than 70 fs and originate from a tip …

Nonlinear photoelectron emission from metallic nanotips is explored in the strong-field
regime. The passage between the multiphoton and the optical field emission regimes is …

We describe the recent emergence of attosecond science, assessing the present state of the
art and discussing several recent examples where attosecond electron dynamics has been …

Full characterization of single ultrashort laser pulses, as needed for attosecond metrology
and spectroscopy, requires precise measurement of the offset between the electric field and …

Petahertz, or lightwave, electronics uses tailored optical waveforms to control charge
carriers in an electronic circuit at petahertz frequencies. This may enable faster processing …
