When solids are exposed to intense laser fields whose forces are comparable to the binding
forces of valence electrons in crystals, nonlinear optics of solids advances to the …

High-harmonic generation in atomic gases has been studied for decades, and has formed
the basis of attosecond science. Observation of high-order harmonics from bulk crystals was …

Attosecond science capitalizes on the extreme nonlinearity of strong fields—driven by few-
cycle pulses—to attain attosecond temporal resolution and give access to the electron …

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 …

Tailoring the electric-field waveform of ultrashort light pulses forms the basis for controlling
nonlinear optical phenomena on their genuine, attosecond timescale. Here we extend …

The mid-infrared spectral region opens up new possibilities for applications such as
molecular spectroscopy with high spatial and frequency resolution. For example, the mid …

The sub-cycle interaction of light and matter is one of the key frontiers of inquiry made
accessible by attosecond science. Here, we show that when light excites a pair of charge …

High harmonic generation (HHG) opens a window on the fundamental science of strong-
field light-mater interaction and serves as a key building block for attosecond optics and …

Recently, intensely driven laser-matter interactions have been used to connect the fields of
strong laser field physics with quantum optics by generating nonclassical states of light …

We theoretically investigate high harmonic generation (HHG) from silicon thin films with
thicknesses from a few atomic layers to a few hundreds of nanometers, to determine the …
