Verfahren zur Herstellung einer Lichtleitfaser auf SiO¶2¶-Basis zur Übertragung einer hohen Lichtleistungsdichte |
摘要 |
An SiO2-based fibre optical waveguide for transmitting a high light power density is produced in a two-step process whereby the preform is produced first and the fibre optical waveguide is drawn from the preform. When the core material (5) is separated with SiCl4 and O2, the compound GeCl4 is added in the quantity necessary to obtain a GeO2 concentration of between 0.001 mol % and 1 mol % in the core (9) and to ensure that the core (9) refractive index differs from the refractive index of the SiO2 by less than 0.001. Alternatively, the preform can be treated with an atmosphere containing H2 after the core material (5) has been separated.
