Nanostructuring of stainless steel by pulsed laser interference lithography — •Lukas Gröner, Martin Stärk, Elke Scheer, and Johannes Boneberg — Universität Konstanz, BW

In pulsed laser interference lithography a laser pulse is divided into several beams which are recombined on the sample to be structured. Due to interference one gets a periodic pattern of high and low intensities. Therefore samples will get hot only in the high intensity regions. We show that this temperature modulation leads to a change in etching resistance which can be used to structure stainless steel surfaces with periods in the micrometer range and depths up to several hundreds of nanometers. As the experiments show not all stainless steel types are usable for this process.
