Description
The role of localized surface plasmon resonance in the laser induced nanoplasmonic fusion is receiving more and more attention [1, 2, 3]. In this work the studies of craters created by high energy femtosecond laser pulses in urethane dimethacrylate (UDMA) - triethylene glycol dimethacrylate (TEGDMA) polymers embedded with plasmonic gold nanoparticles will be presented. A comparison will be done with the same polymer but without gold nanorods. The morphology of the craters was investigated by white light interferometry and the changes of the structure were examined by Raman spectroscopy. Laser irradiations executed with different intensities showed prominent changes in morphology with special regard to the volume of the craters in the presence of gold nanorods [4]. The irradiations carried out by different pulse lengths with intensities in the range of 1018 W/cm2 brought new structures.
