Abstract
Embodiments of the present invention are generally directed to materials processing methods using femtosecond duration laser pulses, and to the altered materials obtained by such methods. The resulting nanostructured (with or without macro- and micro-structuring) materials have a variety of applications, including, for example, aesthetic applications for jewelry or ornamentation; biomedical applications related to biocompatibility; catalysis applications; and modification of, for example, the optical and hydrophilic properties of materials including selective coloring.
Claims20
A method for treating a base metal, comprising:
- exposing a surface region of the base metal to a femtosecond duration laser pulse having a fluence, F, that is sufficient to alter a surface structure of the base metal;
- and
- altering the surface structure of the base metal by creating a nanostructure in the surface.
