摘要： High rate deposition methods comprise depositing a powder coating from a product flow. The product flow results from a chemical reaction within the flow. Some of the powder coatings consolidate under appropriate conditions into an optical coating. The substrate can have a first optical coating onto which the powder coating is placed. The resulting optical coating following consolidation can have a large index-of-refraction difference with the underlying first optical coating, high thickness and index-of-refraction uniformity across the substrate and high thickness and index-of-refraction uniformity between coatings formed on different substrates under equivalent conditions. In some embodiments, the deposition can result in a powder coating of at least about 100 nm in no more than about 30 minutes with a substrate having a surface area of at least about 25 square centimeters.

摘要： Silica grain of desired properties and size is created in a vacuum chamber. Fine silica powder is injected in the chamber or silica powder is formed in situ by combusting precursors. A plasma is formed centrally in the chamber to soften the silica powders so that they stick together and form larger grains of desired size. The grains are collected, doped, fused and flowed into tubes or rods. A puller pulls the tube or rod through a chamber seal into a lower connected vacuum chamber. The tube or rod is converted to rods and fibers or plates and bars in the connected chamber. Fused silica in a crucible tray is subjected to ultrasound or other oscillations for outgassing. Gases are removed by closely positioned vacuum ports.

摘要： The invention gives a coating with a very high vitrification rate. The resulting surface has physicochemical characteristics which are similar to those of fluoride glass. In order to achieve this result, the material constituting the fluoride glass enamel quickly crosses the temperature range between the melting point and the glossy transition temperature. Moreover, the metallic substrate temperature must be high enough to enable an active physiochemical process at the glass-metal interface which results in a correct "hooking". A "hooking" temperature is higher than one where a physical adhesion occurs, which results from Van der Waals interactions without any formation of chemical bonds at the glass-metal interface. The particular chemical reactivity of molten fluorides, which otherwise results in critical problems of corrosion, is in this case a favorable factor which generally reduces the hooking temperature to a level which is far below the glass melting temperature.

摘要翻译： 本发明提供了具有非常高的玻璃化速率的涂层。 所得表面具有与氟化物玻璃相似的物理化学特性。 为了达到这个结果，构成氟化釉的材料迅速地越过了熔点和光泽转变温度之间的温度范围。 此外，金属基板的温度必须足够高以使玻璃 - 金属界面处的活性物理化学过程产生正确的“钩住”。 “挂钩”温度高于发生物理粘附的温度，这是由范德华相互作用产生的，而玻璃 - 金属界面上没有形成化学键。 在这种情况下，熔融氟化物的特定化学反应性，否则会导致严重的腐蚀问题，这是一个有利的因素，通常将挂钩温度降低到远低于玻璃熔融温度的水平。

摘要： The present invention relates to a method and apparatus for fiber and/or fiber perform production and in particular, optical fiber and optical fiber preform production in which a fiber substrate and a multilayered preform can be continuously produced. The layered preform is constructed from particles deposited from one or more aerosol streams containing multicomponent particles wherein individual particles have the ratio of components as desired in the perform layer. Preferably, the components of the aerosol particles have a sub-particle structure in which the subparticle structure dimensions are smaller than the particle diameter and more preferably smaller than the wavelength of light and more preferably on the molecular scale. Preferably, the particles are deposited on the perform substrate via one or more deposition units. Multiple deposition units can be operated simultaneously and/or in series. As the preform is synthesized, it can be simultaneously fed into a drawing furnace for continuous production of fiber. The method can also be used for batch production of fiber preforms and fiber.

摘要： A method for continuously melting a glass by means of a high-frequency electromagnetic field in a melting tube is provided. In this technique, the electromagnetic field is coupled in the melt by means of a coil present within a cooling jacket surrounding the melting tube. A grounded screen and a tube of insulating material are present between the wall of the melting tube and the coil. The melt traverses a heating zone and a refining zone, and a solid elongated body is withdrawn from the bottom of the melting tube.

摘要： The present invention relates to a method for manufacturing a preform for optical fibers, which method comprises the sequential steps of: i) deposition of non-vitrified silica layers on the inner surface of a hollow substrate tube; ii) deposition of vitrified silica layers inside the hollow substrate tube on the inner surface of the non-vitrified silica layers deposited in step i); iii) removal of the hollow substrate tube from the vitrified silica layers deposited in step ii) and the non-vitrified silica layers deposited in step i) to obtain a deposited tube; iv) optional collapsing said deposited tube obtained in step iii) to obtain a deposited rod comprising from the periphery to the center at least one inner optical cladding and an optical core; v) preparation of an intermediate layer by the steps of: * deposition of non-vitrified silica layers on the outside surface of the deposited tube obtained in step iii) or deposited rod obtained in step iv) with a flame hydrolysis process in an outer reaction zone using glass-forming precursors, and subsequently; * drying and consolidating said non-vitrified silica layers into a vitrified fluorine-doped silica intermediate cladding layer; and * in case preceding step iv) was omitted collapsing; to provide a solid rod comprising from the periphery to the center the intermediate layer, at least one inner optical cladding and an optical core; wherein a fluorine-comprising gas is used during the deposition and/or drying and/or consolidating and wherein the intermediate layer has a ratio between the outer diameter of the intermediate cladding layer (C) to the outer diameter of the optical core (A) that is at least 3.5; vi) deposition of natural silica on the outside surface of the intermediate cladding layer of the solid rod obtained in step v) by melting natural silica particles in an outer deposition zone to produce an outer cladding whereby a preform is obtained.
