Siegfried Glenzer,O. L. Landen,Paul Neumayer,Richard W. Lee,Klaus Widmann,S. W. Pollaine,R. J. Wallace,Gianluca Gregori,A. Höll,T. Bornath,R. Thiele,V. Schwarz,Wolf-Dietrich Kraeft,Ronald Redmer +13 more
TL;DR: The forward scattering spectra of a laser-produced narrow-band x-ray line from isochorically heated beryllium show that the plasmon frequency is a sensitive measure of the electron density.

TL;DR: In this paper , the authors achieved a burning-plasma state in the laboratory using a strategy to increase the spatial scale of the capsule through two different implosion concepts and showed that fusion self-heating in excess of the mechanical work injected into the implosions, satisfying several burningplasma metrics.

TL;DR: The first direct measurements of total absorption of short laser pulses on solid targets in the ultrarelativistic regime are reported, showing an enhanced absorption at intensities above 10(20) W/cm(2), reaching 60% for near-normal incidence and 80%-90% for 45 degrees incidence.
