Abstract

This chapter focuses on laser surface processing of silicon, polymethyl methacrylate (PMMA), and magnesium alloy. For silicon, approaches of using femtosecond laser to produce nanostructures and to recrystallize amorphous-Si simultaneously, using excimer laser to generate nanobumps, and using DPSS UV laser to create uniform and consistent microstructures are examined. For PMMA, femtosecond laser is investigated in breaking molecular bonds to tailor wettability ...
