    Abstract: Disclosed are a method for dehydration used in the optical fiber preform manufacturing process, and method and apparatus for manufacturing an optical fiber using the dehydration method. In the dehydration method, when the dehydrating gas is supplied into a tube during the optical fiber preform manufacturing process, dehydration reaction gas included in the dehydration gas is activated using a light source which emits light having a predetermined frequency capable of activating the dehydration reaction gas included in the dehydrating gas into atoms or ions. Then, the method uses the activated dehydration reaction gas generated as a result of the above process to eliminate moisture or hydroxyl group causing optical losses during the optical fiber preform manufacturing process.

    Abstract: Methods for making active laser fibers include the production of an optical fiber with disturbed (or deviated) cylindrical symmetry on the glass surface of the fiber. The methods include a preform containing a central core made of glass. In one embodiment, the preform is circular and surrounded by additional glass rods and an outer glass jacket tube. In a first alternative embodiment, this preform is merged during fiber drawing. In a second alternative embodiment, the preform merged in a process forming a compact glass body with disturbed cylindrical symmetry. This compact preform is drawn into a fiber under conditions maintaining the disturbed cylindrical symmetry.
