Ring plasma jet method and apparatus for making an optical fiber preform |
摘要 |
A method and apparatus for making an optical fiber preform, including injecting a plasma gas source into the first end of a tubular member; generating a ring plasma flame with the plasma gas source flowing through a plasma gas feeder nozzle, the plasma gas feeder nozzle including: an inner tube, an outer tube, wherein the plasma gas source is injected between the inner tube and the outer tube to produce the ring plasma flame, such that at least a portion of the ring plasma flame is directed radially toward the inner surface of the tubular member; traversing the tubular member along the longitudinal axis relative to the plasma flame; depositing at least one soot layer on the interior surface of the tubular member by introducing reagent chemicals into the plasma flame; and fusing all of the soot layers into a glass material on the interior surface of the tubular member.
