Formation of periodic surface structures on dielectrics after irradiation with laser beams of spatially variant polarisation: a comparative study
Antonis Papadopoulos, Evangelos Skoulas, George D. Tsibidis +1
A comparative study is performed to explore the periodic structure formation upon intense femtosecond pulsed irradiation of dielectrics with radially and azimuthally polarised beam…
Modelling periodic structure formation on 100Cr6 steel after irradiation with femtosecond-pulsed laser beams
George D. Tsibidis, Alexandros Mimidis, Evangelos Skoulas +4
We investigate the periodic structure formation upon intense femtosecond pulsed irradiation of chrome steel (100Cr6) for linearly polarised laser beams. The underlying physical mec…
Partial ablation of Ti/Al nano-layer thin film by single femtosecond laser pulse
B. Gakovic, G. D. Tsibidis, E. Skoulas +3
The effects of ultra-short laser pulses on reactive Ti/Al nano-layered thin film were investigated. The thin film composed of alternated titanium and aluminium nano-layers, was dep…
