Abstract

New nanomaterials such as nanobump, nanomesh, nanobelt were generated by thin film processing by interfering femtosecond laser beams. To split and correlate femtosecond laser, a demagnification optical system with a transmission beam splitter was used. Different interference patterns can be generated depending upon the number of beam, magnification factor and period of the transmission grating. Using the system, a material surface can be processed according to the interference pattern. Metallic single- or multi-layered film was used as a target. A nanobump array was applied to field emission device. In addition, periodic structure could be generated inside transparent material in a single process. This scheme is a new technique to generate new nanomaterials and nanostructures using top-down technique.
