Nanoclusters are simpler systems that engulf most of the complexity of the intense laser matter interactions. While the intra-cluster density is solid-like, the bulk density is orders of magnitude smaller. Inter-cluster plasma dynamics offer a rich variety of parameters to tweak the plasma for unusual effects like neutral atom and negative ion acceleration. Rydberg excited states generated in these...
Nanoclusters are strongly ionised at 1016 Wcm−2 to generate even MeV ions. In a dense cluster ensemble a near 100% charge reduction of the ions to form fast neutrals is demonstrated. Neutrals atom emission is quasi-directional and neutralisation is more effective along the laser polarization.
