ABSTRACT:
A system for shaping an optical fiber with various geometries while minimizing unwanted artifacts in the core of the optical fiber. The system facilitates control of sag in the region of the core that is exposed to a beam of optical energy. The sag is reduced, if not eliminated, by maintaining the cross-sectional area of the core that is exposed to the beam at thermal equilibrium.
