    摘要: The invention relates to the production of light-amplifying optical material. Liquid reactant is atomized into droplets using a high velocity gas. The droplets are subsequently introduced into a flame. Reactants are oxidized in the flame and condensed by forming small particles. At least a fraction of said particles is collected and fused to form optical waveguide material, which is subsequently drawn to form an optical waveguide. According to the invention, the velocity of the atomizing gas stream is in the order of the velocity of sound. The high velocity enhances atomization and increases reaction rates in the flame. The residence times are reduced to such a degree that unwanted phase transformations in the produced particles are substantially minimized. Consequently, very homogeneous material is produced. Especially, in the production of erbium-doped silica, low percentage of clustered erbium ions is achieved.
