  • Patent number: 5366937
    Abstract: Optical fiber composed of a glass doped with at least laser-active ions of an element from the rare earths. An optical fiber of glass, preferably a HMF glass, doped with Tm.sup.3+ is operated at 1.48 .mu.m as a fiber laser or amplifier on the laser transition .sup.3 F.sub.4 -.sup.3 H.sub.4. Since this thereby involves a self-saturating transition, the terminal level is emptied in accelerated fashion for a continuous wave mode by co-doping with de-activators, preferably Ho.sup.3+, Tb.sup.3+, Eu.sup.3+ and/or Pr.sup.3+ ions. The pump light wavelength can be selected from the wavelength range from 700 through 890 nm of GaAlAs emission. The optical fiber can be used in optical amplifiers or fiber amplifiers.

  • Patent number: 5256178
    Abstract: A method for manufacturing optical fibers from halide glass is provided. The method includes the steps of drawing a glass mass into a fiber in a dry gas atmosphere which contains a drying agent. In a further step of the process, an OH band which may still be present can be reduced by treating the fiber with a gaseous drying agent.

  • Patent number: 5226940
    Abstract: A process for producing optical fibers of high tensile strength, wherein the fiber is pulled from a glass mass of halide glass and includes surrounding the fiber and mass with a dry gas atmosphere containing a drying agent which reacts with moisture and this dry gas atmosphere includes fluorine-containing agents, in particular NF.sub.3, as the drying agent.
