Effects of Laser Bandwidth in Direct-Drive High-Performance DT-Layered Implosions on the OMEGA Laser
Patel D, Knauer J, Cao D, Betti R, Nora R, Shvydky A, et al.
Phys Rev Lett
. 2023 Sep;
131(10):105101.
PMID: 37739360
In direct-drive inertial confinement fusion, the laser bandwidth reduces the laser imprinting seed of hydrodynamic instabilities. The impact of varying bandwidth on the performance of direct-drive DT-layered implosions was studied...
