Ultraintense Laser Blast Creates True 'Black Metal'

Facebook X LinkedIn Email
Nov. 27, 2006 -- A process involving an incredibly intense burst of laser light that can change the properties of almost any metal to render it black could potentially make everything from fuel cells to a space telescope's detectors more efficient, said the scientists who inadvertently discovered it. "We wanted to see what would happen to a metal's properties under different laser conditions, and we stumbled on this way to completely alter the reflective properties of metals," said Chunlei Guo, assistant professor of optics at the University of Rochester. "We've been surprised by the number of possible...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
