Abstract: | Spatially and temporally resolved emission spectroscopy is used to study the major features of the onset and evolution of
plasmas created by pulsed laser irradiation of targets immersed in liquids. It is shown that double pulse operation provides
an enhanced rate of nanoparticle formation and increases the emission signal from the plasma atoms and ions owing to more
efficient ablation of the target material. The main parameters (density of atoms, electron temperature and density) of laser-induced
plasmas in liquids are estimated. The prospects of laser ablation in liquids as a method for producing nanoparticles are analyzed. |
