Superimposed femtosecond laser pulses can produce periodic nanostructures on various kinds of materials.
This surface phenomenon has attracted considerable interest both for applications in a laser nanoprocessing
technique that exceeds the diffraction limit of light and for understanding unknown physical
mechanisms. We studied the formation mechanism for nanostructuring and developed a control technique.
In this paper, we review our experimental and theoretical nanostructuring results.
