Shock Ignition Laser-Plasma Interactions in Ignition-Scale Plasmas [PDF]
Physical Review Letters, 2021 We use a subignition scale laser, the 30 kJ Omega, and a novel shallow-cone target to study laser-plasma interactions at the ablation-plasma density scale lengths and laser intensities anticipated for direct drive shock-ignition implosions at National Ignition Facility scale.

Laser–plasma interactions for fast ignition [PDF]
Nuclear Fusion, 2014 In the electron-driven fast-ignition approach to inertial confinement fusion, petawatt laser pulses are required to generate MeV electrons that deposit several tens of kilojoules in the compressed core of an imploded DT shell. We review recent progress in the understanding of intense laser plasma interactions (LPI) relevant to fast ignition.
