Observation of ponderomotively driven bow shock using Thomson scattering

Résumé

High energy speckled lasers are known to exert ponderomotive forces on a plasma, this can reduce flow transverse to the propagation of the beams. When coupled with a supersonic flow, this has been shown to lead to formation of a shock that travels against the flow. Experiments conducted on the OMEGA laser facility have used Thomson scattering to observe density and velocity changes consistent with this ponderomotively driven shock. Comparisons of the data with hydrodynamic simulations with the ponderomotive force, particle-in-cell simulations with a full Maxwell field solver, and hydrodynamic simulations without the ponderomotive force show that this shock feature is only reproduced with accounting for the ponderomotive force.
