Attosecond Control of Solid-State High Harmonic Generation Using ω−3ω Fields

The instantaneous power of high harmonic emission calculated using time-dependent density functional theory (blue shaded area) for two values of the relative phase difference of 𝜑 = 1.5𝜋 and 𝜑 = 0.5. The time evolution of the electric field of the combined waveform (red solid curve) is compared with the electric field of the fundamental pulse (black dashed curve).

Photoionization and transient Wannier-Stark ladder in silicon: First-principles simulations versus Keldysh theory

Energy absorbed by electrons as a function of photon energy for the laser field amplitudes of E = 0.5, 0.75, 1.0, 1.5, 2, 3, 4, 5 V/nm (curves from bottom to top) obtained in the TDDFT simulations (solid lines), and using a macroscopic Drude model (dashed lines). The energy is given per one atom of silicon crystal. The calculations were performed for a top-hat temporal shape of laser pulses with duration of 20 fs.

Periodic surface functional group density on graphene via laser-induced substrate patterning at Si/SiO2 interface

Schematics of LIPSS formation and graphene functionalization on SiO2/Si samples. The ratio of intensities of D and G modes in the Raman spectrum of graphene across the LIPSS is shown in the right top, indicating the periodic formation of sp3 carbons in the graphene lattice.

High- speed manufacturing of highly regular femtosecond laser-induced periodic surface structures: physical origin of regularity

Prediction and verification of the LIPSS regularity based on the calculated mean free path LSPP of the surface electromagnetic wave. SEM images obtained with the same magnification are shown for metals studied in the paper with the corresponding 2D-FT (two-dimensional Fourier transform) images.
