A method for preparing a high rare earth doped low loss boron containing glass optical fiber

This invention discloses a method for preparing high rare-earth-doped low-loss boron-containing glass optical fibers. The steps are as follows: weigh glass raw materials containing rare-earth oxides and boron oxide, mix them uniformly, and place them in a high-temperature furnace. First, heat the mixture under a high-purity nitrogen atmosphere, then switch to a high-purity oxygen atmosphere or a high-purity air atmosphere for continued heating. The resulting glass melt is cooled and annealed to obtain a large glass block. The glass is then processed into a preform and placed in an optical fiber drawing furnace for fiber drawing under a high-purity oxygen atmosphere, thus achieving the preparation of high rare-earth-doped low-loss glass optical fibers. This invention eliminates the additional glass matrix absorption in the near-infrared region caused by boron in boron-containing glass optical fibers and also transforms the transition metal impurity ions from a low valence state with broad absorption in the near-infrared region to a high valence state with narrow low absorption in the near-infrared region. Both of these aspects significantly reduce the matrix absorption of boron-containing glass optical fibers, providing possibilities for the application of high rare-earth-doped low-loss glass optical fibers.
