Ablative Acceleration of Laser-Irradiated Thin Foil Targets.

Abstract

Ablative acceleration of thin foil targets at low laser irradiance (10 to the 12th power -10 to the 13th power W/sq cm) are studied experimentally and theoretically. Ablative acceleration of foils up to approximately 10 to the 7th power cm/sec with good hydrodynamic efficiency (20%) have been achieved. These and other results are in good agreement with a simple rocket model. (Author)
