Laser Printing Reflects Light off Tiny Structures for Vibrant Ink-free Colors (4 of 8)

Caption

To demonstrate the working principle of resonant laser printing, the researchers printed several macroscopic images in various color tones. Examples here of several famous paintings laser printed at 500 dots per inch. This material relates to a paper that appeared in the 05 May 2017, issue of Science Advances, published by AAAS. The paper, by X. Zhu at Technical University of Denmark in Kongens Lyngby, Denmark, and colleagues was titled, "Resonant laser printing of structural colors on high-index dielectric metasurfaces."
