Terahertz vortex wave generation in air plasma by two-color femtosecond laser pulses
Maksym Ivanov, Illia Thiele, Luc Bergé +3
We investigate the generation of broadband terahertz (THz) pulses with phase singularity from air plasmas created by fundamental and second harmonic laser pulses. We show that when…
Enhancement of laser-driven ion acceleration in non-periodic nanostructured targets
I. Thiele, J. Ferri, E. Siminos +6
Using particle-in-cell simulations, we demonstrate an improvement of the target normal sheath acceleration (TNSA) of protons in non-periodically nanostructured targets with micron-…
Laser wakefield driven generation of isolated CEP-tunable intense sub-cycle pulses
Evangelos Siminos, Illia Thiele, Christoffer Olofsson
Sources of intense, ultra-short electromagnetic pulses enable applications such as attosecond pulse generation, control of electron motion in solids and the observation of reaction…
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…
Electron beam driven generation of frequency-tunable isolated relativistic sub-cycle pulses
Illia Thiele, Evangelos Siminos, Tünde Fülöp
We propose a novel scheme for frequency-tunable sub-cycle electromagnetic pulse generation. To this end a pump electron beam is injected into an electromagnetic seed pulse as the l…
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…
Spectral dynamics of THz pulses generated by two-color laser filaments in air: The role of Kerr nonlinearities and pump wavelength
A. Nguyen, P. Gonzalez de Alaiza Martinez, J. Dechard +4
We theoretically and numerically study the influence of both instantaneous and Raman-delayed Kerr nonlinearities as well as a long-wavelength pump in the terahertz (THz) emissions…
Theory of terahertz emission from femtosecond-laser-induced micro-plasmas
I. Thiele, R. Nuter, B. Bousquet +5
We present a theoretical investigation of terahertz (THz) generation in laser-induced gas plasmas. The work is strongly motivated by recent experimental results on micro-plasmas, b…
Modelling arbitrarily shaped and tightly focused laser pulses in electromagnetic codes
Illia Thiele, Stefan Skupin, Rachel Nuter
Investigation of laser matter interaction with electromagnetic codes requires to implement sources for the electromagnetic fields. A way to do so is to prescribe the fields at the…
