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 …

Modern optical physics provides means to detect and resolve ultrafast processes on a time
scale of tens of attoseconds. The physical interpretation of such measurements, however …

Combined optical nonlinearity of bound and free electrons in a fast-ionizing medium driven
by ultrashort, mid-infrared (mid-IR) pulses gives rise to a vast variety of ultrafast nonlinear …

Recent studies have demonstrated that the polarization states of high harmonics from solids
can differ from those of the driving pulses. To gain insights on the microscopic origin of this …

A short-pulse, frequency-tunable idler-wave output of a two-stage optical parametric
amplifier is compressed in a gas-filled antiresonance-guiding hollow-core photonic-crystal …

Single microscale filaments were produced in monocrystalline Ia-type diamond by 1030 nm,
300 fs laser pulses tightly focused at NA= 0.3 and different peak powers, visualized by …

The generation of high-order harmonics in bulk solids subjected to intense ultrashort laser
pulses has opened up new avenues for research in extreme nonlinear optics and light …

We reveal the critical effect of ultrashort dephasing on the polarization of high harmonic
generation in Dirac fermions. As the elliptically polarized laser pulse falls in or slightly …

Applying the semiclassical model, we identify two connected effects in intraband high-order
harmonic generation (HHG):(1) propagation time from the point of emission at the source to …

An interesting property of high harmonic generation in solids is its laser polarization
dependent nature which in turn provides information about the crystal and band structure of …
