Femtosecond lasers are a powerful tool for high-precision material processing and functionalization. In my lab, the laser processing led to a range of technological developments, including the so-called black and colored metals, superhydrophillic and superhydrophobic surfaces. In this talk, I will discuss our recent developments in femtosecond laser micro- and nano-scale surface patterning, including the formation dynamics, the drastically altered surface functionalities, and the various applications.
