Atomistic simulations of nanoparticle generation and surface modification by short pulse laser ablation in liquid environment[
Leonid V. Zhigilei, Univ. of Virginia (United States)

The ability of short pulse laser ablation in liquids to produce clean colloidal nanoparticles and unusual surface morphology and microstructure has been employed in a range of practical applications. The results of large-scale molecular dynamics simulations help to uncover the key processes that control the structure of laser-modified surfaces and nanoparticle size distributions generated by pulsed laser ablation in liquids. The simulations are performed for one-component metals, bilayer thin films and alloy targets. The predictions of the simulations include the emergence of Rayleigh–Taylor hydrodynamic instability at the interface between ablation plume and liquid environment, as well as the limited elemental mixing in the colloidal nanoparticles generated by laser ablation of bilayer films.

Leonid V. Zhigilei is a professor of materials science and engineering at the University of Virginia. He studied materials science at Leningrad Polytechnic Institute and earned his PhD degree at Tomsk State University and St. Petersburg State University, Russia. Before joining the faculty of the University of Virginia, he was a postdoctoral researcher in the Department of Chemistry at The Pennsylvania State University. His research interests include multiscale modeling of materials behavior far from equilibrium, mechanisms of phase transformations, nanomaterials, and surface processes.

Tanya Kosc, Univ. of Rochester (United States)

Tanya Kosc is a member of the Optical Materials and Technologies group at the Laboratory for Laser Energetics, where she has been employed for 18 years. She received a B.S. in Physics and a B.A. in German from Case Western Reserve University and her Ph.D. in Optics in 2003 from the Institute of Optics at the University of Rochester under the supervision of the late Prof. Stephen D. Jacobs. Immediately following graduation, she joined the staff at the LLE to perform laser damage testing and within a few years she transferred to the Operations division, where she worked as a Laser System Scientist for nearly a decade. In 2017, she returned to the Optical Materials Technologies group where her work has explored laser-induced damage in liquid crystals and thin films as well as the optical material properties of laser glass and crystals such as KDP and DKDP.
