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.
Abstract: A method for marking or lettering metallic components, specifically those consisting of titanium and titanium alloys, characterized by the steps of: covering the area requiring lettering or marking with a writing ink or writing gel marking or lettering the area by means of a laser scanner.
