Sebastian Uhlig presents the first experimental investigation of self-organized surface
structures (LIPSS) generated by ablation from different (semiconductor and metallic) targets
with an ultrafast white-light continuum (WLC) spreading in wavelength from 400-750 nm. The main
goal is to study the possibility of LIPSS formation upon irradiation with an incoherent and
polychromatic light source (e.g. the WLC) in order to discriminate between the two debated
formation scenarios. The generation of a suitable WLC in terms of sufficient white-light pulse
energy broad spectral bandwidth and low spatial coherence for the LIPSS generation as well
as the characterization of this WLC are additional important objectives of this work.
