Paper Abstract

Various periodic structures have been fabricated on the surface of the transparent glass by a single shot of two or three pulses. When a single shot of two pulses interfered with each other, not only did we get the ordinary grating whose period was agreed well with a theoretical estimation, but also obtained the extraordinary grating whose period was a half of that in the ordinary grating. When a single shot of three pulses interfered with each other, two-dimensional periodic microstructures distributing as a hexagonal lattice have been obtained. Different morphologies of the induced structures such as microvoids, orbicular platforms, and nanotips, could be formed with changing the pulse energy.
