High-repetition-rate source of nanosecond duration kA-current pulses driven by relativistic laser pulses
Michael Ehret, Jakub Cikhardt, Philip Bradford +10
We report the first high-repetition rate generation and simultaneous characterization of nanosecond-scale return currents of kA-magnitude issued by the polarization of a target irr…
Laser-driven ion and electron acceleration from near-critical density gas targets: towards high-repetition rate operation in the 1 PW, sub-100 fs laser interaction regime
V. Ospina-Bohórquez, C. Salgado-López, M. Ehret +34
Ion acceleration from gaseous targets driven by relativistic-intensity lasers was demonstrated as early as the late 90s, yet most of the experiments conducted to date have involved…
High-repetition-rate solid tape target delivery system for ultra-intense laser-matter interaction at CLPU
Michael Ehret, Diego de Luis, Jon Imanol Apiñaniz +6
The VEGA-3 laser system at the Centro de Láseres Pulsados (CLPU) delivers laser pulses up to 1PW at 1Hz repetition rate, focused to intensities up to 2.5e20W/cm2. A versatile and c…
Guided Electromagnetic Discharge Pulses Driven by Short Intense Laser Pulses: Characterisation and Modelling
M. Ehret, M. Bailly-Grandvaux, Ph. Korneev +13
Strong electromagnetic pulses (EMP) are generated from intense laser interactions with solid-density targets, and can be guided by the target geometry, specifically through conduct…
Ablation Holes in Tape Targets Induced by Ultra-Intense Laser Pulses
