Abstract: A substrate is initially positioned in the reaction chamber. One or more gases are introduced into the reaction chamber. A predetermined speed for translating a line of radiation is determined. Continuous wave electromagnetic radiation is then emitted from a continuous wave radiation source. The continuous wave electromagnetic radiation is subsequently focused into a line of radiation extending across the surface of the substrate. The line of radiation is then translated relative to the surface at the constant predetermined speed. The combination of the introduced gas/es and heat generated by the line of radiation causes the gas/es to react and deposit a layer on the surface of the substrate. Undesirable byproducts of the reaction are then flushed from the reaction chamber. This process is repeated until a layer having a predetermined thickness is formed on the surface of the substrate.

Abstract: In an apparatus and a method for marking glass with a laser, the glass is first brought to a temperature above the transformation temperature of the glass. The glass is then acted upon by a laser pulse which produces a mark on the surface of the glass. The peak power of the laser pulse is preferably selected so that it is merely a thermal interaction with the glass surface which occurs. This has the advantage that the material properties of the marked glass remain unchanged compared with the unmarked product.

Abstract: The choices of lenses could be broadened when using lenses of different focus distance and a reduction of size could be accomplished and thus an operation could be made easier by providing a laser-cutting torch in which the laser-cutting torch receives a laser light emitted from a laser oscillator and irradiates the laser light through a nozzle for cutting a targeted cut material.

Abstract: A method of fabricating a fully dense, three dimensional object by direct laser sintering is disclosed. In a chamber with a partial pressure atmosphere, a beam of directed energy melts metallic powder in order to form a solid layer cross section. Another layer of powder is deposited and melted, along with a portion of the previous layer. The energy beam typically is in the form of a laser, scanning along a path resembling a parametric curve or another, arbitrary piecewise parametric curve. In another embodiment, the previous layer is not remelted, thus creating an oxide film that acts as a clean stop to prevent unwanted downward growth.

Abstract: A containment plenum is adapted to deliver laser light to an interaction region of an inhabitable structure to remove material from the structure. The containment plenum includes a plenum housing adapted to be coupled to a source of laser light. The containment plenum further includes a window substantially transparent to the laser light. The window is mounted within the plenum housing to transmit the laser light in a downstream direction and to provide a barrier to upstream transport of particulate matter generated by interaction of the laser light and the structure. The containment plenum further includes a nozzle fluidly coupled to a source of compressed gas. The nozzle is mounted downstream of the window whereby the laser light and the compressed gas are transmitted through the nozzle in the downstream direction to the interaction region of the structure. The containment plenum further includes a resilient interface coupled to the plenum housing and adapted to resiliently contact the structure and to substantially surround the interaction region, thereby confining the material and removing the material from the interaction region.

Abstract: A tool for machining workpieces by motion of the machining tool relative to the workpiece in mutually perpendicular X-Y axes has a support extending in one axis over a work support table and movable in the other axis. A machining tool housing is movable on the support in the other axis. A portion of the housing containing the machining tool is movable with respect to the mounted portion in the other axis within a limited range of motion. A computer control effects operation of drive motors to move the housing along the support and the support along the machining tool table to machine a workpiece supported on said worktable in X and Y axes, and the computer control can also effect operation of another drive motor to rapidly move of the housing portion and machining tool in the other axis when the desired length of motion in the other axis is within its range of motion.

Abstract: A laser welding method and apparatus includes a laser manipulator that directs a laser beam emitted from a laser generator at various predetermined angles toward predetermined positions within a laser work zone. A transport device passes workpieces through the laser work zone where the laser beam manipulator can direct a laser beam at desired interfacing portions of each workpiece to weld those interfacing portions together. The controller is programmed to cause the manipulator to weld the workpieces without halting their motion through the laser work zone.
