    Abstract: A solvent layer is coated on a metal layer carried by a donor substrate, allowing the fabrication of solid metal lines at a high resolution. The laser jetting involves ejecting metal particles, constrained within a solvent membrane, from the metal layer. Once the metal particles have been deposited onto a receiver substrate, the solvent can be evaporated. Since this printing procedure can be performed with the solvent layer in direct contact with the receiver substrate or separated therefrom by a small distance, the resolution of the metal lines can be very high and depends directly on the laser spot size and defocus. The solvent constrains the droplet size of the metal particles, which can increase or maintain the resolution of the laser beam. As this process is a continuous sequence production, the metal line production can be performed at a very rapid rate.

    Abstract: A data generating device includes: a storage; and a controller. The storage is configured to store a plurality of sets of machining condition information in association with respective ones of a plurality of sets of foil information. Each of the plurality of sets of machining condition information specifies a machining condition on irradiation of a laser beam from a laser machining device onto a surface of a workpiece on which a metal foil is placed. Each of the plurality of sets of foil information specifies composition of the foil. The controller is configured to perform: receiving input information specifying composition of a target foil to be subjected to the irradiation of the laser beam as one set of foil information; and identifying one set of machining condition information corresponding to the one set of foil information from the plurality of sets of machining condition information stored in the storage.

    Abstract: A method for marking a thin workpiece is designed to prevent deformation of the workpiece. A plurality of lasers are opposed to respective opposite sides of the workpiece so as to both sides are heat treated. The lasers can operate synchronously with the respective emitted beams aligned with one another. As a result, the workpiece does not exhibit signs of deformation upon the completion of the marking. The workpiece is made either from plastic or metals and has a thickness not exceeding 2 millimeters. The lasers each are configured as either a fiber laser or a gas laser. The marking can be performed by lasers which are configured uniformly or non-uniformly and includes annealing, engraving and ablating. The marking can be performed synchronously or sequentially. The multi-surface marking could also be used to cause “distortion of the surface in a more controlled or desired fashion.

    Abstract: A laser marking method and system, and laser marked object are disclosed. The method includes directing a pulsed laser beam towards an object such that an interface between an oxidized layer and non-oxidized substrate is in a mark zone of the pulsed laser beam, and scanning the pulsed laser beam across the object in a predetermined pattern to create a mark having an L value of less than 40 and a surface roughness that is substantially unchanged compared to adjacent unmarked areas. The system includes a fiber laser generating amplified pulses that are directed towards a galvo-scanner and focusing optic, while the object includes an oxidized surface layer, an underlying non-oxidized substrate, and a mark having an L value of less than 40 with substantially unchanged roughness features.
