Femtosecond Laser Processing of Materials

Femtosecond lasers have been considered as a promising tool for micro/nano-scale patterning of various materials. This book describes the fundamental concepts of lasers laser processing technologies recent advances in forming a variety of micro/nano-metric structures in glasses & metals and their potential application areas. A comparative study among various material processing technologies have been discussed: lithographic technologies vapor deposition technologies and laser processing technologies. The fundamental concepts of femtosecond laser-material interactions are also discussed. The primary focus of the book is to provide in depth ideas about the fabrication of various structures including micro/nano-holes micro/nano-gratings self-organized nanogratings nanocones micro/nano-ripples spherical-shaped nanostructures and ring-shaped micropatterns in a variety of materials. These kinds of micro/nano-structures have definite applications in photonics/optical devices superhydrophobic surfaces 3D optical data storage micro/nano-fluidic devices glass cutting metal colorizing friction reduction and forming metamaterials.
