Description
In this work the effect of the embedded gold nanoparticles was studied on the crater formation during high-intensity femtosecond laser irradiation of urethane dimethacrylate (UDMA) polymers. The polymer targets were prepared without and with gold nanoparticles (in two different concentrations) and were irradiated in different spots with single femtosecond laser pulses of different laser intensities. The ablation of the polymer and crater formation was observed above a certain laser pulse length and intensity threshold. The morphology of the craters was studied by white light interferometry. It was found that the effect of plasmonic nanoparticles is especially prominent at high laser intensities, where 7 times larger craters were formed in their presence, compared to the reference polymer. The effect of gold nanoparticles on the crater morphology and size were evaluated and characterised in details.
