LASER DEPOSITION OF METAL UPON TRANSPARENT MATERIALS Abstract A method and apparatus are disclosed for selectively depositing metal upon materials transparent to laser illum- ination. A laser is oriented to direct a beam of light through a transparent substrate for impact upon a metal surface or reservoir located adjacent the opposite side of the substrate. The laser heats the metal causing vaporization of metal which is then redeposited upon the adjacent surface of the transparent substrate. The laser can be selectively deflected for providing a capability of selected deposition of lines of metal or writing on the substrate. The system and method can be utilized for deposition of other materials, as well.
