The action of a laser on an aluminium targetHenč-Bartolič, Višnja (Avtor) Bončina, Tonica (Avtor) Jakovljević, Suzana (Avtor) Pipić, Davor (Avtor) Zupanič, Franc (Avtor) , Inštitut za kovinske materiale in tehnologije (Lastnik avtorskih pravic) aluminiumlaser ablationthin film depositioninstabilitiestemperaturesA nitrogen laser beam (337 nm, 6 ns (FWHM), (3.2 [plus minus] 0.2) mJ) was focused with a quartz lens (f = 100 mm) onto an aluminium target in air at normal pressure. The laser irradiation and plasma explosion caused a modification to the Al surface and the deposition of a thin film (droplets) onto a glassy carbon plate. The irradiated target and the deposited material were studied with a scanning electron microscope (SEM) and a focused-ion-beam (FIB) device. A crater surrounded by a rim was produced on the spot of maximum irradiation on the aluminium target. The crater, very deep in comparison to its width and thickness, was presumably caused by the Kelvin-Helmholtz and the Rayleigh-Taylor instabilities. The temperatures of the electron and the massive particles were explained.20082017-03-23 15:41:10Znanstveno delo65244ISSN: 1580-2949UDK: 669.71:620.1/.2OceCobissID: 106193664COBISS_ID: 678058ISSN pri članku: 1580-2949NUK URN: URN:SI:UM:DK:Z07NVOA0sl
