The results of theoretical
analysis of the response of solid nanoparticles on the dielectric
surface to the intense ultrashort laser pulse (USLP) action are
presented. The estimation of the ionization degree of
nanoparticles with permanently changing charge on the composition,
intensity and laser pulse duration has been carried out using a
simple analytical model. The dynamics of non-thermal destruction
of nanoparticles and associated changes in the substrate surface
due to the implantation of ions emitted from nanoparticles has
been studied using numerical simulation.
Pateikti kietųjų nanodalelių ant
dielektrinio paviršiaus atsako į ultratrumpųjų lazerinių impulsų
poveikį teorinės analizės rezultatai. Nanodalelių, visam laikui
pakeičiančių krūvį, jonizacijos laipsnis, priklausantis nuo
sudėties, intensyvumo ir lazerio impulso trukmės, įvertintas
naudojant paprastą analizinį modelį. Nanodalelių neterminio
suirimo dinamika ir susiję pokyčiai substrato paviršiuje dėl jonų,
išspinduliuotų iš nanodalelių, implantacijos nagrinėti
pasitelkiant skaitmeninį modeliavimą.
