By: Yongguang Huang Femtosecond laser texturing has proved to be a particularly powerful method for creating a wide variety of surface structures on the metal films, such as a hollow microbump-nanojet sturcture and disk-column-nanodroplet structure on the gold films. The process of femtosecond laser texturing does not rely on material removal, but on hydrodynamic flow […]
