Challenges in laser surface texturing and patterning

  • Pattern resolution (sub-wavelength), uniformity, and repeatability;
  • Processing speed, throughput and system cost;
  • Durability of laser-generated textures;
  • Nanostructures’ design-ability;
  • Realisation of user-defined nanostructures;
  • Physics behind the dynamic phenomena in ultrafast laser processing;
  • Nanoscale optical materials’ properties.
