TL;DR: In this article, the authors report the achievement of fusion fuel gains exceeding unity on the US National Ignition Facility using a high-foot implosion method, which is a manipulation of the laser pulse shape in a way that reduces instability in the implosion.

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.
