Direct Laser Interference Patterning (DLIP) is a method that implements physical phenomena of interference to produce periodic structures on surfaces by transferring the shape of the pattern directly to the material by selective laser ablation. Recent developments of the DLIP method will be presented in this talk. The structuring of thin metallic films and bulk materials using nano- and picosecond laser systems will be introduced by going through different optical setups and industrial systems which have been recently developed. Several technological applications including tribology, biological interfaces, thin film organic solar cells and electrodes as well as decorative elements and safety features will be discussed and summarized in this presentation.
