The laser-induced fabrication of nanostructures with feature sizes below the optical diffraction limit is possible for almost any material for arbitrary sample geometries and dimensions by exploiting nonlinear excitations or optical near-field interactions. This overview highlights historical milestones, explains the underlying physical processes and associated challenges, and discusses current and future trends in the field of ultrafast laser nanostructuring.
