Abstract: Embodiments of the present invention are directed to methods and systems for micromachining a conical surface. In one embodiment, such a system may include a rotating platform for receiving a long line of laser illumination, a mask having a predetermined pattern comprising a sector of a planar ring, the mask being positioned on the rotating platform, a workpiece stage having a rotational axis for rotating a removably-affixed workpiece comprising a conical surface, wherein the sector comprises the planar image of the conical surface, an excimer laser for producing a laser beam, a homogenizer for homogenizing the laser beam in at least a single direction, at least one condenser lens, a turning mirror and at least one projection lens.

Abstract: This invention results from the realization that a laser can remove the protective layer(s) from the glass or fused silica optical fiber core and cladding more effectively and more reliably than chemical or mechanical means. This invention teaches methods of using laser beams to remove the protective layers of fibers without significantly damaging the optical and mechanical properties of the fiber and without leaving an excessive amount of residual ablation debris on the fiber while providing careful control of the laser energy. This method thereby allows users to safely strip protective layers off sensitive fibers, such as fibers used for fiber Bragg gratings (FBG). This method allows stripping of the protective layers from single fibers and from multi-fiber ribbon cables. It also allows stripping of the protective layers at an end section of the cable or in a middle section (mid-span).

Abstract: A new method and apparatus for moving an excimer laser beam relative to a workpiece to control the wall profile of laser machined features, such as holes and grooves. An excimer laser beam is displaced relative to a workpiece in a substantially circular motion and the substantially circular motion is further displaced relative to the workpiece to correspond to a desired shape.
