Ultrafast laser-matter interactions in metals and dielectrics

Ultrafast lasers and especially femtosecond lasers offers new possibilities in the field of micromachining as they allow precise machining with almost no collateral damage around the machined features. Furthermore, the pulse duration (<500fs) is smaller than the atomic vibration period of virtually all materials which results in unique laser/matter interactions. The research project will look at better understanding the surface features obtained after femtosecond laser irradiation of metals and dielectrics. This includes ripple formation, microvoids formation, nano and microstructure modification, etc. In particular, two beam interference will be used to better control the morphologies obtain after irradiation.
