A sealing device and method are described herein that can be used to manufacture a hermetically sealed glass package. In one embodiment, the hermetically sealed glass package is suitable to protect thin film devices which are sensitive to the ambient environment (e.g., oxygen, moisture). Some examples of such glass packages are organic emitting light diode (OLED) displays, sensors, and other optical devices. The present invention is demonstrated using an OLED display as an example.

A localized deposition system is provided comprising a substrate support, a feed material supply, a feedstock laser source, a substrate laser source, and a deposition control system. The feedstock laser source is configured to heat feed material positioned for localized deposition on the deposition surface of the substrate. The substrate laser source is configured to heat a localized portion of the substrate. The deposition control system is programmed to synchronize the relative movement between the deposition surface of the substrate and the localized deposition position of the feed material supply with operation of the feedstock laser source, the substrate laser source, and the feed material supply to execute a deposition operation. Methods of localized deposition are also provided.
摘要:
A method of sealing a plurality of frame-like frit walls disposed between two substrates. The frit walls are arranged in rows and columns and divided into groups, each group being sealed by a separate laser beam. Several strategies are disclosed for the order in which the frit walls are heated and sealed by a laser beam to optimize the efficiency of the sealing process.

Gradient-index (GRIN) lens fabrication employing laser pulse width duration control, and related components, systems, and methods are disclosed. GRIN lenses can be fabricated from GRIN rods by controlling the pulse width emission duration of a laser beam emitted by a laser to laser cut the GRIN rod, as the GRIN rod is disposed in rotational relation to the laser beam. Controlling laser pulse width emission duration can prevent or reduce heat accumulation in the GRIN rod during GRIN lens fabrication. It is desired that the end faces of GRIN lenses are planar to facilitate light collimation, easy bonding or fusing of the GRIN lens to optical fibers to reduce optical losses, polishing to avoid spherical aberrations, and/or cleaning the end faces when disposed in a fiber optic connector, as non-limiting examples.

The invention is directed to a method and apparatus for joining together pieces of low thermal expansion glass to form parts that can be used in the manufacturing of mirror blanks. The parts are then used as a basis for the fabrication, using the method described herein, of hexagon sub-assemblies that would then be joined for assembly into mirror blanks.

Articles having multiple surface depressions and process and apparatus for making the same. The invention is useful in making, inter alia, glass plates having a surface depression array which can be used in semiconductor and electronics manufacture, drug discovery and display devices.
摘要:
A method for closing the holes on the end face of a nano-engineered fiber having a core, a cladding with non-periodically disposed voids, and at least one of a coating and a buffer, comprises the steps of: (i) cleaving the fiber portion, thereby forming a cleaved end face; and (ii) applying a predetermined amount of energy via a laser beam to the cleaved end face, the amount of energy being sufficient to collapse and seal the voids exposed at the cleaved end face only to a depth of less than 11 μm.
