Summary
Three photonic laser techniques to transfer colour images with high resolution to metal surfaces: oxidation of metal and interferences, formation of nanoparticles and plasmon resonance, structuring of a periodic circuit and diffraction of light.
Scientists at the ITMO University of St. Petersburg have developed a method to produce various colour effects on a metal surface with a single laser. It is a question of controlling the processing parameters in order to control the correct amount of heat delivered and, consequently, the temperature obtained. The study consisted of three processes based on different physical effects to produce images in colour.
