A combination of the ultrashort high-energy pulsed las. syst. with exceptional beam quality and a novel DOE enables simultaneous production of 2601 spots organized in the square-shaped 1×1mm matrix in less than 0.01ms.By adjusting the las. and processing parameters each spot can contain LIPSS,ripples,including high-spatial freq. LIPSS and low-spatial freq. LIPSS.DOE placed before galvanometric scanner allows easy integration and stitching of the pattern over larger areas.The LIPSS formation was monitored for using fast infrared radiometry for verification of real-time quality control possibilities.During the LIPSS fabrication,solidification plateaus were observed after each las. pulse,which enables process control by monitoring heat accumulation or plateau length using a new signal derivation approach.Analysis of solidification plateaus after each las. pulse enabled dynamic calibration of the measurement.
