Characterization of a controlled plasma expansion in vacuum for laser driven ion acceleration

Résumé

We present experimental and numerical results on the formation of a controlled plasma density gradient in front of a solid target irradiated with a subpicosecond, moderate intensity laser pulse. Interferometry with femtosecond probe is used to map the temporal evolution of the spatial density distribution of the generated plasma. Experimental results are found to be in good agreement with 1D1/2 hydrodynamic simulations. Moreover, these numerical simulations enable us to determine the impact of such a heating beam on the target rear surface and to correlate the plasma gradient that can be produced on the illuminated surface with the position of the shock wave in the bulk.
