Strong-field focusing of high-energy particles in beam-multifoil collisions
Aimé Matheron, Doug Storey, Max F. Gilljohann +25
Extreme beams of charged particles and photons, reaching ultrahigh densities or producing intense gamma-ray bursts, are central to accelerator physics, laboratory astrophysics, and…
Ultra-Short flying-focus
Jérôme Touguet, Igor A. Andriyash, Lucas Rovige +1
Achromatic flying-focus enables programmable control of intensity peak velocity, with applications in ultrafast optics. However, spatiotemporal coupling inherently elongates ultras…
Optical modelling of shaped laser pulses in plasma
Igor A. Andriyash, Cedric Thaury
This work provides a brief review of the numerical methods for modelling the optical propagation of an ultrashort, intense laser pulse in plasmas and ionizable gases. These methods…
Demonstration of ultra-low emittance beams in a kHz laser wakefield accelerator and application to electron diffraction
J. Monzac, S. Smartsev, J. Huijts +12
We present a compact, cost-effective method for measuring the emittance of kHz-repetition-rate laser-wakefield accelerated electron beams using a permanent solenoid. The measured n…
Advanced Shaping of Quasi-Bessel Beams for High-Intensity Applications
Jérôme Touguet, Igor Andriyash, Ronan Lahaye +4
Quasi-Bessel beams produced by axiparabolas are increasingly used in high-intensity laser applications, yet their longitudinal profiles exhibit unwanted oscillations that limit the…
Experimental Demonstration of Dephasing Reduction in an Optically Guided Laser-Plasma Accelerator
Ronan Lahaye, Igor A. Andriyash, Julien Gautier +5
Laser-plasma accelerators offer a compact means of producing high-energy electron beams, but their performance is fundamentally limited by dephasing between the accelerated electro…
