Abstract
Methods and systems for high speed surface blackening and/or coloring are disclosed, including generating electromagnetic radiation from an ultrashort pulse laser (UPL); coupling the electromagnetic radiation from the UPL to a scanner comprising a scanning and focus range, wherein the scanner is configured to receive the electromagnetic radiation from the UPL and to scan and focus the electromagnetic radiation onto a sample; using a computer to adjust the pulse repetition rate and the energy of the UPL; using a five degree of freedom motorized stage to position the sample; using a dichroic filter positioned between the scanner and the sample; focusing an imager through the dichroic filter and onto the surface of the sample; using a processor to acquire and process images to monitor the surface blackening and/or coloring of the sample within the scanning and focus range of the electromagnetic radiation. Other embodiments are described and claimed.
