TL;DR: Omega is a 60-terawatt, 60-beam, frequency-tripled Nd:glass laser system designed to perform precision direct-drive inertial-confinement-fusion experiments and the acceptance tests demonstrated exceptional performance throughout the system.

TL;DR: In this article, techniques have been developed to improve the uniformity of the laser focal profile, to reduce the ablative Rayleigh-Taylor instability, and to suppress the various laser-plasma instabilities.
Journal ArticleDOI

TL;DR: In this paper, a magnetic field of 80 kG was embedded in the target and was subsequently trapped and compressed by the imploding conductive plasma, and the observed ion temperature and fusion yield were enhanced by 15% and 30%, respectively.

TL;DR: Boehly et al. as discussed by the authors performed a series of singlemode, Rayleigh-Taylor instability growth experiments performed on the OMEGA laser system and reported a laser-irradiation nonuniformity of 4%-7% over a 600 μm diam region defined by the 90% intensity contour.
