Disclosed herein is an orthodontic article, a method of making an orthodontic article and an apparatus for making the orthodontic article. The orthodontic article is made by laser welding the work piece, comprising a bracket body and a the pad, together. The article thus formed includes a laser-welded seal around the perimeter of the adjoining areas between the pad and the bracket body. In an exemplary embodiment the apparatus of the invention, makes a series of closely spaced spot welds. The spot welds, in an exemplary embodiment, are significantly overlapped that they form a seal around the entire perimeter of the work piece adjoining areas. The spot welds, in an exemplary embodiment, are significantly overlapped that they form a hermetic seal between the pad and the bracket body. In other exemplary embodiments, the process of manufacturing orthodontic articles is automated and controlled by a computer and computer software.

Method and apparatus for welding orthodontic article and an orthodontic article

A three color laser system employs a diode pumped Nd:YAG or Nd:YLF laser to provide a green output beam and to pump two Ti:S lasers. One Ti:S laser emits a tunable red beam, while the second emits a near infrared beam. The near infrared beam is frequency doubled by a NLO device to provide a tunable blue output beam. The beams may be directed to separate optical fibers or to a single fiber. A reversed Cassegrainian mirror arrangement is used to combine a plurality of beams for transmission in a single optical fiber.

Three color laser

An air cooled, flash lamp pumped, solid state laser device wherein heating devices are disposed on the laser rod at both ends to heat and temperature stabilize the laser rod. The solid state, laser rod is longer than the arc length of the flash lamp. The ends of the laser rod can be heated directly by winding heating wire, such as Nichrome, around each end or by applying heat through thermal conductive supports. A feedback loop is provided to maintain temperature of the solid state laser rod, which is preferably Alexandrite, within a desired range of 80.degree. C. to 120.degree. C.
