Dynamics of nanosecond-laser-induced melting of tin in vacuum, air, and water

Popis výsledku v původním jazyce

We measured the nanosecond-laser-induced damage thresholds of tin in vacuum,air,and water. The threshold fluence is found to be ~ 0.1 J/cm2 regardless of the environment unlike more refractory metals when threshold values in water are considerably higher than those in air.Analysis of the morphology and chemical composition of the irradiated surface as well as numerical simulations of tin laser heating demonstrate that the observed surface modification is due to melting but not oxidation.For the case of water environment,the conductive heat transfer to water is found to play only a minor role in tin heating and melting. The simulations show also that the formation of a water vapor layer near the tin surface occurs at a considerably higher fluence, above 0.15 J/cm2,and thus the surface damage is not affected by scattering of the incident laser light by the vapor–liquid interface,typical for more refractory metals.
