Fiber optic union, an apparatus for making said union with a controlled laser, and methods of making and using thereof

摘要

Method and apparatus for providing a linearly or non-linearly tapered bore, with minor undulations within the bore wall, in vitreous tubing includes a laser and elements for focusing the laser onto the vitreous tubing. The vitreous tubing is rotated in the laser beam and is moved in the laser beam to provide a taper in the interior bore. The power of the laser beam is controlled and a lens, to provide a desired width of the beam at the vitreous tubing to produce the desired features, appropriately focuses the laser beam.
