Multilayered fluorescent wafer for laser lighting and display, and method of manufacturing

A molding device and a molding method for an optical fiber preform are provided. The molding device includes a rotating mechanism, an extrusion mechanism, and a cylinder mold that is of a cylindrical structure with two ends each having an opening. After a hollow cladding sleeve is obtained by rotating the cylinder mold through the rotating mechanism, a molten core glass is then reversely extruded into the cladding sleeve in the cylinder mold from bottom to top by the extrusion mechanism to prepare the optical fiber preform.

The laser glass doped with high concentration of mid-infrared fluoroindate includes the raw materials in parts by mole percentage: 27-38 parts of InF, 13 parts of ZnF, 10 parts of GdF, 19 parts of BaF, 5 parts of CaF, 10 parts of SrF, 5-15 parts of Al(PO)and 1-11 parts of ErF.

Laser glass doped with high concentration of mid-infrared fluoroindate and preparation method thereof

A high strength glass fiber is prepared by following steps: weighing raw materials according to a mass percentage of 50-60% silica sol, 24-31% aluminum sol, 8-11% magnesia, 4-5% calcium oxide, 0.1-2% titanium dioxide, 0-0.5% ferric oxide, 0.5-2% niobium pentoxide, 0.5-1.5% antimony trioxide, 0.3-1.5% bismuth nitrate, and 0.1-0.5% boric acid. Deionized water is added. The raw material undergoes mixing by ball milling, spray-drying, calcining, isostatic pressing, melting, and wire-drawing. The invention adopts silicon sol, aluminum sol and bismuth nitrate. Through ball milling and spray-drying, silicon aluminum barium plasmas is evenly coated on surface of other oxide powders. Then nano particles, of silica, alumina and bismuth oxide are obtained by calcining. Under the effect of the high specific surface energy of nano particles, and the close contact of each component, high strength glass fiber is obtained in relatively low fiber drawing temperature while the glass melting temperature and time are significantly reduced.
