how to break through the diffraction limit has always been an important problem. In recent years
nanospheres auxiliary femtosecond laser near field processing with characteristic size beyond the diffraction limit is recognized and developed gradually. It can fabricate nanoholes on the substrate surface of which scale is smaller than the incident laser diffraction limit
and can realize large area processing. In this paper
we will focus on the metal nanospheres and dielectric nanospheres
and introduce the study of nanospheres assisted femtosecond laser near field processing.
