摘要
A regular micro-apparatus covered with periodic nanohole, nanoridge, and ripple structures on silicon bulk (with crystal orientation of 110) was formed by micromachining with a tightly focused beam of a femtosecond laser with a wavelength of 800 nm, a repetition rate of 1 kHz, and a pulse length of 130 fs in air. We used laser direct writing technology to form periodic double-row nanohole structures, and the laser was focused with a 10x focusing objective lens (NA = 0.3). We investigated the relationship between the width of structures and the speed of processing to provide knowledge of the evolution of the nanohole and nanoridge structures.
