LEAD-CONTAINING FLUORIDE GLASS, OPTICAL FIBER AND PROCESS FOR PRODUCING IT |
摘要 |
Lead-containing fluoride glass comprises 50-70 mol% of ZrF4, 3-5 mol% of LaF3, 0.1-3 mol% of YF3, and 2-15 mol% of NaF and/or LiF and/or CsF, where LaF3+YF3=4.5-6 mol%, and further comprises lead. An optical fiber comprises a core made of the lead-containing fluoride glass and a cladding surrounding the core. A process for producing an optical fiber comprises forming a base material for a core of the lead-containing fluoride glass, forming a base material for a cladding of fluoride glass containing 30-60 mol% of HfF4 and drawing the base materials into an optical fiber at a drawing temperature of 315-340 .degree.C. |
