    Abstract: In a method for producing a fluorophosphate optical glass comprising melting a glass raw material to give a molten glass, and refining, homogenizing and then quickly quenching the molten glass to produce the fluorophosphate optical glass, even if the glass is flown from a refining tank that is set to a high temperature to an operation tank that is set to a low temperature, bubbles are not generated in the glass.The content of Fe in terms of Fe2O3 and the content of Cu in terms of CuO is controlled so that the total of the contents of Fe and Cu is 20 ppm or more, and the obtained fluorophosphate optical glass has such transmittance property that the internal transmittance in terms of a thickness of 10 mm becomes 98% or more at a wavelength region of at least from 400 to 500 nm.

    Abstract: High optical quality glass windows, particularly of low melting and low viscosity glasses and substantially free of defects, particularly adapted for high energy laser applications, are made by stirring the molten glass during cooling without the use of a mechanical stirrer within the glass, by rotating the mold or crucible in which the glass is cooling, using a motion which is not entirely a circular and rotary motion.

    Abstract: To overcome problems of fabricating conventional core-clad optical fibre from non-silica based (compound) glass, it is proposed to fabricate non-silica based (compound) glass optical fibre as holey fibre i.e. one contining Longitudinal holes in the cladding. This removes the conventional problems associated with mismatch of the physical properties of the core and clad compound glasses, since a holey fibre can be made of a single glass composition. With a holey fibre, it is not necessary to have different glasses for the core and cladding, since the necessary refractive index modulation between core and cladding is provided by the microstructure of the clad, i.e. its holes, rather than by a difference in materials properties between the clad and core glasses. Specifically, the conventional thermal mismatch problems between core and clad are circumvented. A variety of fibre types can be fabricated from non-silica based (compounds) glasses, for example: single-mode fibre; photonic band gap fibre; highly non-linear fibre; fibre with photosensitivity written gratings and other refractive index profile structures; and rare-earth doped fibres (e.g. Er, Nd, Pr) to provide gain media for fibre amplifiers and lasers.

    Abstract translation: 为了克服从非二氧化硅（复合）玻璃制造常规的包芯光纤的问题，提出了制造非二氧化硅基（复合）玻璃光纤作为多孔纤维，即在包层中连续的纵向孔。 这消除了与芯和包覆复合玻璃的物理性质失配相关的常规问题，因为多孔纤维可以由单一玻璃组合物制成。 使用多孔光纤，由于芯和包层之间必需的折射率调制由包层的微结构即其孔提供，而不是通过材料性质的差异来提供用于芯和包层的不同的玻璃。 在包层和核心眼镜之间。 具体来说，芯和包层之间常规的热失配问题被规避。 各种纤维类型可以由非二氧化硅（化合物）玻璃制成，例如：单模纤维; 光子带隙光纤; 高度非线性的纤维; 具有光敏写入光栅的纤维和其他折射率分布结构; 和稀土掺杂光纤（例如Er，Nd，Pr），为光纤放大器和激光器提供增益介质。

    Abstract: The disclosure is directed to an all glass method that frustrates the internal reflection on the outside diameter of an optical fiber's glass cladding thus allowing the light to be directed to a light absorbing material/ medium and allowing the desired light in the core of the fiber to be preserved with no loss. The frustration is achieved by having at least one glass frustrater in glass-to-glass contact with the outermost cladding layer of the optical fiber. The glass frustrater is made of a glass that has a glass transition point lower that both the core and cladding glasses of the fiber. Chalcogenide and phosphate glasses are among the glasses suitable for this application.
