CA 2275706

Phosphate free, Er/Yb co-doped borosilicate glass compositions and optical devices made from said compositions are disclosed; said compositions comprising, for 100 parts by weight of: 60 to 70 parts by weight SiO2 or SiO2 + GeO2 with SiO2 always being greater than 40 parts by weight, 8 to 12 parts by weight of B2O3, 10 to 25 parts by weight M2O wherein M2O is an alkali metal oxide, 0 to 3 parts by weight of BaO, 0.1 to 5 parts by weight Er2O3, and from 0.1 to 12 parts by weight of Yb2O3 and from 0 to less than 5 parts by weight F; and within which, the boron atoms are of tetrahedral spatial coordination.

Cette invention se rapporte à des compositions de verre à base de borosilicate dopé à la fois par Er et Yb, ne contenant pas de phosphates, ainsi qu'à des dispositifs optiques fabriqués à partir de telles compositions. Ces compositions contiennent, pour 100 parts en poids, 60 à 70 parts de SiO¿2? ou de SiO¿2? + GeO¿2?, le SiO¿2? représentant toujours plus de 40 parts en poids; 8 à 12 parts en poids de B¿2?O¿3?; 10 à 25 parts en poids de M¿2?O, où M¿2?O est un oxyde de métal alcalin; 0 à 3 parts en poids de BaO; 0,1 à 5 parts en poids de Er¿2?O¿3?; 0,1 à 12 parts en poids de Yb¿2?O¿3? et moins de 5 parts en poids de F, les atomes de bores de ces compositions possédant une coordination spatiale tétraédrique.
