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…
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…
Enhanced target normal sheath acceleration using colliding laser pulses
J. Ferri, E. Siminos, T. Fülöp
Laser-solid interaction can lead to the acceleration of protons to tens of MeV. Here, we show that a strong enhancement of this acceleration can be achieved by splitting the laser…
