  • Method for the production of colored structures of a glass
    Patent number: 7168268
    Abstract: A method for the manufacture of colored structures of a glass, particularly for applying an inscription to the glass, by locally heating volume elements of the glass by means of a laser beam. The glass contains ions of metals which, in the form of submicroscopic particles, color the glass wherein the local heating of the non-doped glass is accomplished through a solution or gel of a metallic salt which transmits the laser beam well and is directly contacted with a surface of the glass.
    Type: Grant
    Filed: April 17, 2002
    Date of Patent: January 30, 2007
    Assignee: Sator Laser GmbH
