  • Patent number: 10131016
    Abstract: A laser system includes a buffer material at an entry surface of a substrate in which laser-induced channels are formed. The laser beam propagates through the buffer material and impinges the substrate with a central axis of the laser beam at an oblique angle of incidence. The buffer material has a refractive index that may be closer to that of the substrate than is the refractive index of the atmosphere, such as air, in which the laser system operates. The buffer material facilitates forming laser-induced channels at relative large angles with respect to the substrate surface by attenuating energy loss or other effects on the laser beam that are normally caused by the mismatch in refractive index between the environment and the substrate in the absence of the buffer material.

  • Patent number: 10029421
    Abstract: A 3D printer device utilizing at least one Quantum Cascade Laser (QCL) image head having at least one beam focused in a focal plane of the device for building on a surface of the device a 3D model of a target object from a digital image. The inventive 3D printer is more compact in size due to the use of QCL image heads, which provides focused wavelengths of QCLs matching the absorption properties in plastics for more efficient absorption of the radiant energy. Each QCL channel power in the inventive 3D printer can be doubled by combining two lasers with a polarization beam splitter. The QCL image head is provided with Pulse Width Modulation (PWM) for compensating for imaging speed. The invention includes a method for scaling up the building speed of 3D printing regardless of detail level. The invention discloses an affordable 3D printer using QCL technology while maintaining high standards of resolution, use of quality materials, and rapid building speeds.

  • Patent number: 9881817
    Abstract: Methods, tools and systems for patterning of substrates using charged particle beams without photomasks, without a resist layer, using multiple different processes (different chemistry processes and/or different ones of material deposition, removal and/or modification) in the same vacuum space, wherein said processes are performed independently (without cross-interference) and simultaneously. As a result, the number of process steps can be reduced and some lithography steps can be eliminated, reducing manufacturing cycle time and increasing yield by lowering the probability of defect introduction. Also, because such processes are resist-less, layer-to-layer registration and other column control processes can be performed by imaging previous-layer features local to (or in contact with) features to be written in a next layer as designated by the design layout database.

  • Patent number: 9776906
    Abstract: An internal feature can be laser machined in strengthened glass sheets or panels by first laser machining a first scribe in a first surface proximate to the internal feature to be laser machined. The internal feature can be then laser machined by positioning a beam waist of a laser beam proximate to an opposite second surface by focusing the laser beam through the strengthened glass panel from the first surface. The internal feature is laser machined by repositioning the beam waist from the second surface to the first surface while removing material from a kerf surrounding the internal feature. When the laser beam waist is finally positioned proximate to the first surface material, the internal shape formed by the laser machining is easily and cleanly removed from the surrounding glass.

  • Patent number: 9744625
    Abstract: The present invention involves laser machining polymer substrates to form a stent with laser parameters that minimize damage to the substrate in a surface region adjacent to the machined edge surface. The wavelength and pulse width are selected for this unique application and they can be controlled to minimize the surface modifications (such as voids, cracks which are induced by the laser-material interaction) which contribute to the variation in mechanical properties with distance from the edge surface, bulk mechanical properties, or a combination thereof.

  • Patent number: 9580851
    Abstract: In at least one implementation, a method for forming openings for a stitched seam in a composite panel having an outer layer, and a substrate behind the outer layer includes providing a laser beam onto the substrate, with the laser beam forming an opening through the substrate but not through the outer layer, and moving at least one of the laser or the substrate relative to the other so that a new opening can be formed that is spaced from the already formed opening. Successive openings can be formed in desired locations around the panel to facilitate subsequent panel stitching. In at least some implementations, the laser may form such openings while stitches are formed in the panel, wherein a stitch is provided in a previous opening while or nearly at the same time the laser forms a different opening for a subsequent stitch.
