摘要： This process provides a new way to embed rare earth fluorides into silica (or germania-doped silica) glasses by solution chemistry. Embedding rare earth fluorides into a silica (or germania-doped silica) glasses comprises the following steps. The first step forms a porous silica core preform by OVD process. The second step submerges the preform into an aqueous solution of rare earth ions. The third step removes the preform from the solution and washes the outside surfaces of the preform. The fourth step submerges the preform into an aqueous solution of a fluorinating agent, such as ammonium bifluoride, HF or KF. Rare earth trifluorides precipitate out from the solution and deposit on the wall of pores. This is followed by drying.

摘要： A quartz glass doped with rare earth element, aluminium and further fluorine, and endowed with various characteristics such as practicable luminescent properties, high amplification gain, achievement of wider band, size reduction of elements, fusibility and connectivity of quartz glasses with each other, and so forth. This glass is not accompanied with crystallization inherent in this type of doped quartz glass in the course of its producton, so that it is transparent of course and contains no residual bubbles. Since the production process comprises a combination of a technique for forming a porous glass with a method of solution impregnation, it is possible to produce readily a quartz glass doped with both rare earth element and aluminum, having high purity and excellent transparency, and being useful as an active optical element.

摘要： Disclosed is a method of forming a doped glass body. The glass body is formed by adding a dopant to a glass preform, at least part of which has interconnective pores. The porous preform is immersed in a solution of a salt of the dopant dissolved in an organic solvent having no OH groups. The solvent is removed, and the porous glass preform is heat treated to consolidate it into a non-porous glassy body containing the dopant dispersed throughout at least a portion of the body. An OH-free solvent is selected because of its beneficial effect on the preform during the drying step. Whereas OH-containing solvents such as water and alcohol caused cracking and/or flaking of the outer surface of the porous preform following the drying step, an undamaged surface is formed by the present invention.
