Therefore, a coating of nano-particles on foil targets could lead to an enhanced ablative acceleration. The results of experiments performed with PALS laser system (125 J, ~250 ps at 1.3 μm) with a focused intensity of about 1014W/cm2 are presented. 15 μm thick Polyethylene teraphthalate (C10H8O4)n or PET foils show an almost 40% increase in target movement when coated with a layer of gold nano-particles. Comparison between targets with coating of bulk gold and nano-gold shows about 15% higher target movement in gold nano-particle coated PET targets as compared to bulk gold coating. This result is a clear indication of enhanced laser energy absorption in targets with nano-structured surface of gold. We also present evidence to show the effect of nano-particle coating on lateral thermal conduction.
