    Abstract: A color image is fused on a hard surface by a laser beam. A first color layer of toner particles is fused in accordance with a first color separation of a color image at a first screen angle. A second color layer of toner particles is fused in accordance with a second color separation of a color image at a second screen angle. A third color layer of toner particles is fused in accordance with a third color separation of a color image at a third screen angle. A fourth color layer of toner particles is fused in accordance with a fourth color separation of a color image at a fourth screen angle. The screen angles and offsets of the focal point of the laser beam are selected for each color to optimize the colors fused onto the surface.

    Abstract: The invention relates to a method for the laser-assisted introduction of metal ions by ion exchange and diffusion and for the colored internal scribing of glass. With the aid of this method, it is possible for both colorless pixels with a different refractive index from their surroundings and colored pixels, for example in silver stain or copper ruby, to be produced in glass. The processes which are required to produce the metal particles which cause the glass coloration, namely ion exchange and diffusion of metal ions into the glass, the reduction of these ions to form atoms and the aggregation of the atoms to form metal particles, take place in a locally delimited manner as a result of locally delimited heating. For this purpose, by way of example, a film which has been printed over its area with printable diffusion ink is stuck to the glass which is to be provided with a colored pattern, and the glass surface to which the film has been stuck is locally heated with focussed laser radiation. Metal particles are formed in the heated regions, and thereby colored pixels are formed in the glass without any damage or local melting of the glass. The laser irradiation can also be controlled in such a way that only the ion exchange and the diffusion of the ions which have been introduced into the glass by this exchange take place in a locally limited manner and colorless pixels are formed. The pixels can be used to mark, scribe and decorate glass and also to produce passive optical elements, for example transmission gratings.

    Abstract: A marking method is provided which permits an easy detecting of the presence of a mark without using a specific reading apparatus, and is capable of avoiding a damage as well as a strength deterioration of an object material. The marking method comprises: preparing a marking object; converging, into the marking object, a laser beam having a wave length range so chosen that the laser beam can transmit through a material forming the marking object, and then effecting a multiple photon absorption; and moving a converging position of the laser beam, in a manner such that an area, whose refractive index is changed due to the multiple photon absorption, can form a diffraction pattern capable of diffracting a visible light.
