Abstract:The present work utilizes Direct Laser Interference Patterning (DLIP) in conjunction with a polygon scanner system to fabricate micro and nanostructures on the surface of nickel foils. A picosecond pulsed laser source with an average power of ∽470 W is used to pattern line‐like structures having spatial periods of 11.0 and 25.0 µm and a maximum structure depth of up to 15 µm. The scanning speed and the number of consecutive scans, ranging from 5 to 500, are varied in order to assess their influence on the stru… Show more
