Title (EN) BISMUTH CONTAINING FLUOROPHOSPHATE GLASS AND METHOD FOR MAKING THEREOF
(FR) VERRE AU FLUOROPHOSPHATE CONTENANT DU BISMUTH ET PROCEDE D'ELABORATION
Abstract:
(EN) New and improved compositions of doped and co-doped bismuth fluorophosphate glasses for lasers is disclosed that have a high refractive index (nD) of approximately 1.6 and higher, high transmission in the near infrared part of the spectrum, and a wide glass forming domain. The disclosed glass systems A1(PO3)3- Ba(PO3)2- Bi(PO3)3- BaF2 + RFx + dopands use dopants from the group of oxides and or fluorides of rare earth elements Nd Er, Yb, Tm, Tb, Ho, Sm, Eu and Pr as we as MnO and mixtures thereof over 100 percent (wt%) of the glass-base composition. These glasses have high chemical durability, radiation resistance, efficiency of laser use in the infrared and blue spectrum, and improved duration of luminescence.
(FR) Compositions nouvelles et améliorées à base de verre au fluorophosphate contenant du bismuth de type codopé, pour lasers, avec indice de réfraction élevé (nD) d'environ 1,6 ou plus, transmission élevée dans la partie du spectre proche de l'infrarouge, et domaine de formation de verre large. Les systèmes de verre considérés A1(PO3)3- Ba(PO3)2- Bi(PO3)3- BaF2 + RFx + dopants utilisent des dopants du groupe des oxydes et/ou des fluorures des éléments des terres rares Nd Er, Yb, Tm, Tb, Ho, Sm, Eu et Pr ainsi que MnO y compris les mélanges correspondants à raison de plus de 100 % en poids de composition à base de verre. Ce type de verre présente une durabilité chimique élevée, une résistance aux rayonnements élevée, une haute efficacité en application laser dans la partie du spectre proche de l'infrarouge et du bleu et une durée de luminescence améliorée.
