Shock Ignition Laser-Plasma Interactions in Ignition-Scale Plasmas [PDF]

open access: yesPhysical 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 ignition of pulverized coals [PDF]

open access: yesCombustion and Flame, 1994
Abstract We present a novel experiment to study the ignition of pulverized coal. A dilute stream of particles is dropped into a laminar, upward-flow wind tunnel with a quartz test section. The gas stream is not preheated. A single pulse from a Nd:YAG laser is focused through the tunnel and ignites the fuel. The transparent test section and cool walls
