Terahertz emission from submicron solid targets irradiated by ultraintense femtosecond laser pulses
J. Déchard, X. Davoine, L. Gremillet +1
Using high-resolution, two-dimensional particle-in-cell simulations, we investigate numerically the mechanisms of terahertz (THz) emissions in submicron-thick carbon solid foils dr…

THz generation from relativistic plasmas driven by near- to far-infrared laser pulses
J. Déchard, X. Davoine, L. Bergé
Terahertz pulse generation by ultra-intense two-color laser fields ionizing gases with near- to far-infrared carrier wavelength is studied from particle-in-cell (PIC) simulations.…

Terahertz emission from laser-driven gas-plasmas: a plasmonic point of view
I. Thiele, B. Zhou, A. Nguyen +8
We disclose an unanticipated link between plasmonics and nonlinear frequency down-conversion in laser-induced gas-plasmas. For two-color femtosecond pump pulses, a plasmonic resona…
