Abstract
In drawing an optical waveguide, the blank is heated by a beam of laser radiation which has substantially zero power from the axis of the blank to a prescribed radial position and substantially uniform power from that position to a greater radial position. A rotating spinner splits radiation from the laser into two rotating beams, the paths of which are made to be non-intersecting with the axis of the blank being drawn. A conical reflector forms the radiation into a circumferential beam through which the blank passes.
