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-…

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…
