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…
Decoupling acceleration and wiggling in a laser-produced Betatron source
Julien Gautier, Igor Andriyash, Andreas Döpp +11
Betatron radiation is produced in Laser Plasma Accelerators when the electrons are accelerated and simultaneously wiggle across the propagation axis. The mechanisms of electron acc…
Quasi-monoenergetic multi-GeV electron acceleration in a plasma waveguide
Ronan Lahaye, Kosta Oubrerie, Olena Kononenko +3
Laser-plasma accelerators present a promising alternative to conventional accelerators. To fully exploit the extreme amplitudes of the plasma fields and produce high-quality beams,…
Highly-efficient electron ponderomotive acceleration in underdense plasmas
Lorenzo Martelli, Olena Kononenko, Igor Andriyash +16
Laser-plasma accelerators represent a promising technology for future compact accelerating systems, enabling the acceleration of tens of pC to above GeV over just a few centim…
Use of spatiotemporal couplings and an axiparabola to control axial energy deposition velocity
Aaron Liberman, Ronan Lahaye, Slava Smartsev +5
This paper presents the first experimental realization of a scheme that allows for the tuning of the axial energy deposition velocity of a focal spot with relativistic intensity. B…
Spatiotemporal pulse characterization with far-field beamlet cross-correlation
Slava Smartsev, Sheroy Tata, Aaron Liberman +9
We present a novel, straightforward method for spatiotemporal characterization of ultra-short laser pulses. The method employs far-field interferometry and inverse Fourier transfor…
Controlled acceleration of GeV electron beams in an all-optical plasma waveguide
Kosta Oubrerie, Adrien Leblanc, Olena Kononenko +9
Laser-plasma accelerators produce electric fields of the order of 100 GV/m, more than 1000 times larger than radio-frequency accelerators. Thanks to this unique field strength, the…
Axiparabola: a new tool for high-intensity optics
Kosta Oubrerie, Igor A. Andriyash, Ronan Lahaye +3
An axiparabola is a reflective aspherical optics that focuses a light beam into an extended focal line. The light intensity and group velocity profiles along the focus are adjustab…
