Effects of hydrogen concentration in ablator material on stimulated Raman scattering, two-plasmon decay, and hot electrons for direct-drive inertial confinement fusion
Laser plasma instabilities, such as stimulated Raman scattering (SRS) and two-plasmon decay (TPD), are basic phenomena in intense laser science and applications.In direct-drive inertial confinement fusion (ICF) where a fuel capsule is imploded by high-power lasers, SRS and TPD are generally problematic because hot electrons (HEs) generated by SRS a
