Ultrashort-pulse laser (femtosecond), provide the ability to create texturations on the surface of all materials with micrometric accuracy.
Femtosecond laser treat the surface of all material families from the hardest to the most fragile, giving them new features through multi-scale micrometric texturations.
Functionalizing a surface consists of modifying its characteristics to give it new properties.
Change of the contact angle of the surface according to the law of Cassie-Baxter in order to obtain a hydrophobic / water-repellent function
The shark skin effect is the combination of the topography of its micro-scales and the movement of the animal’s skin
The periodic sub-wavelength structure of the surface gives it broadband AR properties
