Maxwell-consistent, symmetry- and energy-preserving solutions for ultrashort laser pulse propagation beyond the paraxial approximation
P. González de Alaiza Martínez, G. Duchateau, B. Chimier +4
We analytically and numerically investigate the propagation of ultrashort tightly focused laser pulses in vacuum, with particular emphasis on Hermite-Gaussian and Laguerre-Gaussian…
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…
Broadband terahertz emission from two-color fs-laser-induced microplasmas
Illia Thiele, Pedro Gonzalez de Alaiza Martinez, Rachel Nuter +3
We investigate terahertz emission from two-color fs-laser-induced microplasmas. Under strongest focusing conditions, microplasmas are shown to act as point-sources for broadband te…
Ultrashort filaments of light in weakly-ionized, optically-transparent media
L. Berge, S. Skupin, R. Nuter +2
Modern laser sources nowadays deliver ultrashort light pulses reaching few cycles in duration, high energies beyond the Joule level and peak powers exceeding several terawatt (TW).…
