Abstract

Femtosecond lasers are a powerful tool for high-precision material processing. Femtosecond laser induced micro- and nano-scale surface patterning can also lead to surface functionalization. In my lab, the laser processing led to a range of technological developments, including the so-called black and colored metals. In this talk, I will discuss our recent developments in laser-induced structural coloring and its various applications. I will also discuss some of our recent work on non-laser-induced structural coloring and applications. Other associated surface functionalization induced by laser irradiation, such as superhydrophillic and superhydrophobic surfaces, will also be discussed.
