The multilayered fluorescent wafer includes a fluorescent glass layer, a metal reflective film layer with high reflectivity, a sealing silver paste layer with high thermal conductivity, and a metal substrate layer, the layers disposed sequentially from top to bottom.

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.
