Abstract
The formation of free-standing gold nanosieves by ablation with ultra-short laser pulses is demonstrated. Macroscopic areas are generated fast and efficiently by the application of a parallel production technique. The technique is based on a lens array formed by self-assembling quartz microspheres on a thin metal foil. The evaporated foils have a final thickness of 400 nm, and the hole spacing is set by the diameter of the microspheres (∼7 μm) while the pore size is ∼700 nm. The characteristic spacing of the generated hole structure is verified by an optical diffraction technique.
