Double layer acceleration of ions with differently charged states in a laser induced plasma

Popis výsledku v původním jazyce

The electric feld driven acceleration of plasma ions is an intrinsic efect in laser-induced plasma plumes and is responsible for the generation of high-energy ions. At high laser fuences (≥2 J/cm2 ), multiply charged ions are formed and afect the plume expansion dynamics. In this paper, we used kinetic energy-resolved mass spectrometry to investigate the relative abundance and kinetic energy distributions of singly- and doubly-charged ions produced by KrF-laser ablation of nine diferent oxide targets. The doubly charged metal ions with a lower mass-to-charge (m/z) ratio show narrow energy distributions at high average kinetic energies coinciding with the cutof energies for the singly-charged ion distributions. The observation suggests that the recombination of higher charged ions plays a prominent role in the formation of the high-energy tail for singly-charged ions.
