Intrinsic femtosecond structure of extreme contrast harmonic pulses: influence on relativistic laser-solid interactions
C. Aparajit, Anandam Choudhary, Ankit Dulat +7
Extreme intensity contrast is considered essential for ultraintense, femtosecond laser excitation of solid targets, in particular for studies with structured or ultra-thin targets.…
Radiation Pressure Driven Ion Weibel Instability and Collisionless Shocks
Anna Grassi, Mickael Grech, Francois Amiranoff +2
The Weibel instability from counterstreaming plasma flows is a basic process highly relevant for collisionless shock formation in astrophysics. In this Letter we investigate, via t…
Energy dispersion in radiation pressure accelerated ion beams
M. Grech, S. Skupin, A. Diaw +2
We address the problem of energy dispersion of radiation pressure accelerated (RPA) ion beams emerging from a thin (solid) target. Two different acceleration schemes, namely phase-…
Coulomb explosion of uniformly charged spheroids
M. Grech, R. Nuter, A. Mikaberidze +6
A simple, semi-analytical model is proposed for non-relativistic Coulomb explosion of a uniformly charged spheroid. This model allows us to derive the time-dependent particle energ…
Anomalous Self-Generated Electrostatic Fields in Nanosecond Laser-Plasma Interaction
L. Lancia, M. Grech, S. Weber +15
Electrostatic (E) fields associated with the interaction of a well-controlled, high-power, nanosecond laser pulse with an underdense plasma are diagnosed by proton radiography. Usi…
High-quality ion beams by irradiating a nano-structured target with a petawatt laser pulse
M. Grech, S. Skupin, R. Nuter +2
We present a novel laser based ion acceleration scheme, where a petawatt circularly polarized laser pulse is shot on an ultra-thin (nano-scale) double-layer target. Our scheme allo…
