Ponderomotive-expulsion: toward creating an electron-free volume
Smrithan Ravichandran, Teresa Cebriano, José Luis Henares +5
We describe a demonstration of a prototype approach to clear the laser focal volume of free electrons and disable their atomic and molecular sources. Employing two temporally separ…
Laser Interactions with Gas Jets: EMP Emission and Nozzle Damage
Philip Wykeham Bradford, Valeria Ospina-Bohorquez, Michael Ehret +18
Understanding the physics of electromagnetic pulse emission and nozzle damage is critical for the long-term operation of laser experiments with gas targets, particularly at facilit…
Currents from relativistic laser-plasma interaction as novel metrology for system stability of high-repetition-rate laser secondary sources
Michael Ehret, Jose Luis Henares, Iuliana-Mariana Vladisavlevici +8
This work shows for the first time experimentally the close relation between return currents from relativistic laser-driven target polarization and the quality of the relativistic…
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…
Ablation Holes in Tape Targets Induced by Ultra-Intense Laser Pulses
Michael Ehret, Jon Imanol Apiñaniz, Jose Luis Henares +5
We present a theoretical modelling able to predict the dimensions of mm-sized through-holes produced in interactions of the 1 PW high-power 30fs Ti:Sa laser VEGA-3 with tape target…
Laboratory evidence of the halting of magnetic reconnection by a weak guide field
S. Bolanos, R. Smets, S. N. Chen +10
Magnetic reconnection occurs when two plasmas having co-planar but anti-parallel magnetic fields meet. At the contact point, the field is locally annihilated and the magnetic energ…
