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…
Collisionless Larmor Coupling and Blob Formation in a Laser-Plasma Expanding into a Magnetized Ambient Plasma
Lucas Rovige, Robert S. Dorst, Ari Le +8
Collisionless Larmor coupling is a fundamental process in space and astrophysical plasmas that enables momentum transfer between an expanding plasma and a magnetized ambient medium…
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…
Transfer Learning for Analysis of Collective and Non-Collective Thomson Scattering Spectra
T. Van Hoomissen, J. Alhuthali, A. M. Ortiz +9
Thomson scattering (TS) diagnostics provide reliable, minimally perturbative measurements of fundamental plasma parameters, such as electron density () and electron temperatur…
Direct Measurement of Electron Heating in Electron-Only Reconnection in a Laboratory Mini-Magnetosphere
Lucas Rovige, Filipe D. Cruz, Timothy Van Hoomissen +6
We report on the experimental observation of electron heating in electron-only magnetic reconnection in laser-driven laboratory mini-magnetospheres on the Large Plasma Device (LAPD…
Differential pumping for kHz operation of a Laser Wakefield accelerator based on a continuously flowing Hydrogen gas jet
Joséphine Monzac, Slava Smartsev, Julius Huijts +13
Laser-Wakefield Accelerators (LWFA) running at kHz repetition rates hold great potential for applications. They typically operate with low-energy, highly compressed laser pulses fo…
