The study found that AnnsNd:YAG pulsed laser can be used to deposit thin films in a vacuum and generate nanoparticles in water. The nanoparticles produced by laser ablation have dimensions of around 25 nm and concentrations of around a few mg/ml, with the stoichiometry of NiTi alloy validated in the thin films and nanoparticles.
AnnsNd:YAG pulsed laser was used to deposit thin films in a vacuum and to generate nanoparticles in the water of Ni, Ti, and NiTi alloys. Laser ablation was measured in terms of removing mass per laser pulse. The laser-generated plasma in vacuum was characterized in terms of temperature and energy of emitted particles. The ablation in water produces nanoparticles with dimensions of the order of 25 nm and solutions with concentrations of the order of some mg/ml. The NiTi alloy stoichiometry is well reported in the deposited thin film and in the composition of the produced nanoparticles.
