High-harmonic generation from solids
Web1 de jan. de 2024 · This section provides an in-depth introduction to high-harmonic generation (HHG) in solids. We will focus on the mechanisms used to describe HHG in solids and discuss related properties such as the cutoff of the harmonic spectra or the role of the dephasing time. 2.1. Interband polarization and intraband currents: An introduction Web10 de mai. de 2024 · We study the polarization states of high-order harmonics emitted from a-cut ZnO crystals driven by femtosecond mid-infrared laser pulses. The polarization states of even and odd harmonics are sensitive to structural symmetries of the crystal.
