Laser ablation in liquid

In the paper "Shock waves emitted at the collapse of a laser-induced cavitation bubble in the vicinity of a free surface", we investigated the dynamic of a cavitation bubble induced by laser ablation in liquid in the vicinity of a free surface. The observation was conducted using high-speed laser stroboscopic videography in photoelasticity mode. We showed the bubble contracted faster in the vertical direction and formed a flat bubble at the minimum contraction. At the collapse, the bubble emitted multiple shock waves.

In this study, rhenium/rhenium oxide nanoparticles (Re/ReO3NPs) have been produced for the first time in ultrapure water by using Femtosecond Pulsed Laser Ablation in Liquid (fsPLAL) method. X-Ray Diffraction (XRD) measurements and results obtained for NPs show the existence of well-crystallized peaks and preferred phases. Re NPs have hexagonal structure while ReO3 NPs have the perovskite-like cubic crystal structures. The Re/ReO3 ratio is also determined to be 53/47 with ~ 20 nm crystallite size, while pure ReO3 crystallite sizes were measured to be ~ 25 nm.

We characterized their shape and morphology using transmission electron microscopy (TEM), and confirmed their crystalline structure with X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) in combination with energy-dispersive X-ray spectroscopy (EDX) elemental mapping.

Photoelastic images of pulsed laser ablation in liquid were simulated by Finite Element Method. The real stress distribution in the target was deduced from the photoelastic images. The simulation result can represent to some extend the photoelastic images taken by the experiment.

We studied to prepare silver nanoparticle substrate for Surface-Enhance Raman Scattering (SERS). Silver nanoparticles were produced by laser ablation of silver plate in ethanol. The average size of silver nanoparticles is 15nm. The silver nanoparticle colloid was allowed to dry on a silicon wafer to prepare SERS substrate. Using the silver nanoparticle substrates we could obtain SERS spectrum of Rhodamine 6G molecules adsorbed on silver nanoparticles. The Raman signal was enhanced strongly by our SERS substrate.
