Sheng Jiang,Liangliang Ji,Heather A. Audesirk,Kevin George,Joseph Snyder,Andrew Krygier,Patrick Poole,Christopher Willis,R. L. Daskalova,Enam Chowdhury,Nathan S. Lewis,Douglass Schumacher,Alexander Pukhov,Richard R. Freeman,Kramer Akli +14 more
TL;DR: The interaction of a high-contrast short-pulse laser with a flat target via periodic Si microwires yields a substantial enhancement in both the total and cutoff energies of the produced electron beam.

TL;DR: In this article, a free-electron laser-based X-ray diffraction geometry was combined with laser-driven compression to elucidate the importance of shear generated during shock compression on the occurrence of phase transitions.
Journal ArticleDOI
Effects of front-surface target structures on properties of relativistic laser-plasma electrons.
TL;DR: Three-dimensional particle-in-cell simulation studies apply to short-pulse, high-intensity laser pulses, and indicate that a judicious choice of target front-surface geometry provides the realistic possibility of greatly enhancing the yield of high-energy electrons while simultaneously confining the emission to narrow (<5°) angular cones.
Journal ArticleDOI
On the origin of super-hot electrons from intense laser interactions with solid targets having moderate scale length preformed plasmas
TL;DR: In this paper, the authors use particle-in-cell modeling to identify the acceleration mechanism responsible for the observed generation of super-hot electrons in ultra-intense laser-plasma interactions with solid targets with pre-formed plasma.
