Generation of attosecond electron bunches and X-ray pulses from few-cycle femtosecond laser pulses
Julien Ferri, Vojtech Horný, Tünde Fülöp
Laser-plasma electron accelerators can be used to produce high-intensity X-rays, as electrons accelerated in wakefields emit radiation due to betatron oscillations.Such X-ray sourc…
Optimized computation of tight focusing of short pulses using mapping to periodic space
Elena Panova, Valentin Volokitin, Evgeny Efimenko +9
When a pulsed, few-cycle electromagnetic wave is focused by optics with f-number smaller than two, the frequency components it contains are focused to different regions of space, b…
Effects of oblique incidence and colliding pulses on laser-driven proton acceleration from relativistically transparent ultrathin targets
Julien Ferri, Evangelos Siminos, Laurent Gremillet +1
The use of ultrathin solid foils offers optimal conditions for accelerating protons from laser-matter interactions. When the target is thin enough that relativistic self-induced tr…
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-…
Radiation emission in laser-wakefields driven by structured laser pulses with orbital angular momentum
J. L. Martins, J. Vieira, J. Ferri +1
High-intensity X-ray sources are invaluable tools, enabling experiments at the forefront of our understanding of materials science, chemistry, biology, and physics. Laser-plasma el…
Enhancement of betatron X-rays through asymmetric laser wakefield generated in transverse density gradients
Julien Ferri, Xavier Davoine
Laser wakefield acceleration of electrons usually offers an axisymmetry around the laser propagation axis. Thus, the accelerating electrons that are focused on axis often execute s…
