• An alternative concept for accelerating thin foils to high velocity has been proposed and tested. The thin ( 10   μ m ) Al foil has been accelerated by the ablative plasma generated by means of the third harmonic ( λ = 0.438   μ m , τ = 250   ps ) of the iodine laser pulse of the energies of 75 and 190 J irradiating a massive Cu target. Two separation distances of the foil from the massive target of 100 and 500   μ m were used. It has been shown that this method of an indirect, two-step acceleration, named as the reversed acceleration scheme, can be more effective than the classic, direct-drive approach. The Al flyer foil has reached a velocity of ∼ 1.3 × 10 7   cm / s , i.e., significantly higher than that in the comparable "classic" ablative acceleration experiment.
