Acceleration of a thin (10 or 20 μm) plastic foil by 120 J, 0.438 μm, 0.3 ns laser pulse of intensity up to 1015 W/cm2 has been investigated. It is shown that the introducing a high-Z dopant to the foil causes an increase in the ablating plasma density, velocity, and collimation which, in turn, results in a remarkably higher kinetic energy and energy fluence of the flyer foil.

Abstract
Acceleration of a thin (10 or 20 μm) plastic foil by 120 J, 0.438 μm, 0.3 ns laser pulse of intensity up to 1015 W/cm2 has been investigated. It is shown that the introducing a high-Z dopant to the foil causes an increase in the ablating plasma density, velocity, and collimation which, in turn, results in a remarkably higher kinetic energy and energy fluence of the flyer foil.File in questo prodotto:
