    摘要: A system and method depositing metal to form a three-dimensional (3D) part on a substrate (140). A wire (120) is moved relative to a location on the substrate while a laser heats a proximal end of the wire at the location using a laser beam (130). The laser causes the wire and substrate to reach a melting point of the wire to fuse the wire at the location on the substrate. The wire can be preheated by passing a current through the wire.

    摘要: A new technique and Method of Direct Coulomb Explosion in Laser Ablation of Semiconductor Structures in semiconductor materials is disclosed. The Method of Direct Coulomb Explosion in Laser Ablation of Semiconductor Structures provides activation of the "Coulomb explosion" mechanism in a manner which does not invoke or require the conventional avalanche photoionization mechanism, but rather utilizes direct interband absorption to generate the Coulomb explosion threshold charge densities. This approach minimizes the laser intensity necessary for material removal and provides optimal machining quality. The technique generally comprises use of a femtosecond pulsed laser to rapidly evacuate electrons from a near surface region of a semiconductor or dielectric structure, and wherein the wavelength of the laser beam is chosen such that interband optical absorption dominates the carrier production throughout the laser pulse. The further application of a strong electric field to the semiconductor or dielectric structure provides enhancement of the absorption coefficient through a field induced fedshift of the optical absorption. The use of this electric field controlled optical absorption is available in all semiconductor materials and allows precise control of the ablation rate. When used in conjunction with nanoscale semiconductor or dielectric structures, the application of a strong electric field provides for laser ablation on sub-micron lateral scales.

    摘要: A charged particle beam and a laser beam are used together to micromachine a substrate. A first beam alters the state of a region of the work piece, and the second beam removes material whose state was altered. In one embodiment, an ion beam can create photon absorbing defects to lower the local ablation threshold, allowing the laser beam to remove material in a region defined by the ion beam. The combination of laser beam and charged particle beam allows the creation of features similar in size to the charged particle beam spot size, at milling rates greater than charged particle processing because of the increased energy provided by the laser beam.
