Laser-intensity-spike-dominated hot electron generation from two-plasmon decay instability driven by moderate-bandwidth pulses
C. Yao, Z. H. Cai, X. Wang +34
Our direct-drive-relevant experiments on the low-coherence Kunwu laser facility identify two-plasmon decay (TPD) as the primary source of hot electrons, and demonstrate for the fir…
Resonance density range governs two-plasmon decay saturation and enables hot-electron prediction in inertial confinement fusion
C. Yao, J. Li, L. Hao +6
The saturation level of parametric instabilities critically determines their impact on fusion plasmas. We identify the resonance density range of two-plasmon decay as the critical…
Convective Nature of the Stimulated Raman Side Scattering in Inertial Confinement Fusion
F. -X. Zhou, C. -W. Lian, R. Yan +4
The absolute growth of Stimulated Raman side scattering (SRSS) predicted by previous theories appeared to be surprisingly absent in the recent ignition-scale direct-drive experimen…
Efficient generation of divergent and collimated hot electrons via a novel multi-beam two-plasmon decay and stimulated Raman scattering mechanism
K. Y. Meng, Z. H. Cai, J. Li +5
In inertial confinement fusion (ICF) implosions, the preheating risks associated with hot electrons generated by laser plasma instabilities (LPI) are contingent upon the angular ch…
