Femtosecond Laser and Its Application in Micromachining

It is reviewed that the shortening development of laser pulse and the application of femtosecond laser precise fabrication in this article. The mechanisms and characteristics of femtosecond laser in micromachining are mainly described. Its unique traits of femtosecond laser beam primely illuminate that it is a perfect tool in microfabrication, which can fabricate polymer, and enables fabrication of three-dimensional microstructures in various transparent materials, except a unique application in the biology field. Finally, the prospects of femtosecond laser fabrication are also discussed.
