    Abstract: PROBLEM TO BE SOLVED: To obtain glass having a large size and containing CaO and P 2 O 5 . SOLUTION: A crack-free glassy object is formed by forming an aqueous or water-containing dispersion, adding P 2 O 5 and CaO, adding an acid in order to reach a pH-value of 2±0.5, adding tetraethyl ortho-silicate (TEOS), titrating the sol by means of ammonium hydroxide till pH 4.1±0.2, pouring the sol so obtained into a mold, substituting a solvent in the gel pores with an aprotic solvent, setting gel in a pressure chamber, fluxing an inert gas into the pressure chamber, heating the pressure chamber over a programmed time period to achieve pre-determinate temperature and pressure values lower than the relevant critical value of the gel solvent, evaporating the solvent, depressurizing the pressure chamber, washing by an inert gas, cooling the dried gel, taking out the gel from the pressure chamber and heating at a prefixed temperature to sinter.

    Abstract: PURPOSE:To provide a low loss and good resistance to radiation by specifying the respective refractive indices of a core, clad and elliptical jacket and the size in the prescribed part at specific values and forming the clad of silica glass contg. fluorine. CONSTITUTION:An optical fiber for maintaining plane of polarization has the relation expressed by the inequality I where the respective refractive indices of a core 21, a clad 22 and an elliptical jacket 23 are designated as n1, n2, n3 and has the relation expressed by the inequality II where the radius of the core is designated as T, the thickness of the clad as delta1T, and the total min. thickness of the clad and the elliptical jacket as delta2T. Such relations are obtd. by forming the core 21 and the support 24 of high purity silica, making the clad 22 into the constitution consisting essentially of SiO2, contg. fluorine, and contg. no B2O5 and making the jacket 23 into the constitution consislting essentially of SiO2 and contg. P2O5 and B2O3. A low loss and good resistance to radiation are thus obtd.
