Micro-fabrication of high aspect ratio periodic structures on stainless steel by picosecond direct laser interference patterning

[Display omitted] We have studied the fabrication of line-like and pillar-like periodic microstructures on stainless steel by means of direct laser interference patterning. A picosecond (10ps) pulsed Nd:YAG laser operating at 1064nm wavelength was used to produce the microstructures with spatial per...
