  • Patent number: 10470843
    Abstract: A dental laser treatment system includes a treatment laser beam and a pilot (e.g., aiming/marking) laser beam sharing a collinear beam path, where the beam path is guided by a guidance system through a handpiece/main chamber assembly having a beam exit. A laser beam presence detector is removably affixed to or within the handpiece/main chamber assembly. The laser beam presence detector provides feedback to a computer which can control actuation of the treatment laser beam and the pilot laser beam, and the beam guidance system. The computer performs a search for determining the center location of the beam exit based on the feedback and controls the beam guidance system to guide the beam path approximately to the center of the beam exit, thereby providing automatic alignment of the laser beam with the beam exit or an optional hollow waveguide.

  • Patent number: 9969199
    Abstract: Techniques or processes for providing markings on products are disclosed. In one embodiment, the products have housings and the markings are to be provided on sub-surfaces of the housings. For example, a housing for a particular product can include an outer housing surface and the markings can be provided on a sub-surface of the outer housing surface yet still be visible from the outside of the housing. Since the markings are beneath the surface of the housing, the markings are durable.

  • Patent number: 9919380
    Abstract: Methods of and devices for forming edge chamfers and through holes and slots on a material that is machined using a laser, such as an ultrafast laser. The shaped material has predetermined and highly controllable geometric shape and/or surface morphology. Further, a method of and a device for preventing re-deposition of the particles on a material that is machined using a laser, such as an ultrafast laser. A fluid is used to wash off the particles generated during the laser machining process. The fluid can be in a non-neutral condition, with one or more chemical salts added, or a condition allowing the coagulation of the particles in the fluid, such that the particles can be precipitated to avoid the reattachment to the machined substrate.

  • Patent number: 9909925
    Abstract: Embodiments of the present invention generally relate to apparatus for and methods of measuring and monitoring the temperature of a substrate having a 3D feature thereon. The apparatus include a light source for irradiating a substrate having a 3D feature thereon, a focus lens for gathering and focusing reflected light, and an emissometer for detecting the emissivity of the focused reflected light. The apparatus may also include a beam splitter and an imaging device. The imaging device provides a magnified image of the diffraction pattern of the reflected light. The method includes irradiating a substrate having a 3D feature thereon with light, and focusing reflected light with a focusing lens. The focused light is then directed to a sensor and the emissivity of the substrate is measured. The reflected light may also impinge upon an imaging device to generate a magnified image of the diffraction pattern of the reflected light.
