摘要:
New and improved compositions of doped and co-doped germanium fluorophosphate glasses for laser hosts and fiber amplifiers have a high refractive index (nD) 1.67-1.70, high transmission in the near infrared part of the spectra (to 6 micron) and a wide glass-forming domain. These glass systems [BaGe4O9—Ba(PO3)2—RFx] contain (mol %): BaF2, CaF2, MgF2, BiF3, PbF2 of 10 to 70 percent and GeO2 7.31 to 58.48 percent, P2O5 of 4.81 to 38.50 percent, BaO of 7.86 to 62.94 percent where dopants and co-dopants are over 100 percent (in wt %): Nd2O3(NdF3) of 0.5 to 15 percent, Er2O3(ErF3) of 0.2 to 12 percent, Yb2O3(YbF3) of 1.0 to 15 percent, Ho2O3(HoF3) of 1.0 to 10 percent, Pr2O3(PrF3) of 0.5 to 12 percent, Tm2O3(TmF3) of 0.2 to 10 percent, Tb2O3(TbF3) of 0.1 to 10 percent, MnO(MnF2) of 0.5 to 20 percent.

摘要:
Devices are made comprising a tin-phosphorous oxyfluoride glass, which has been exposed to light, preferably shorter in wavelength than the absorption edge of the glass, to change the refractive index change of the glass. The glasses can be used to form planar and fiber devices, including core/clad structures for guiding light.
摘要:
A host material for Tm3+-doping is provided. The host material is a fluorophosphate glass having a non-zero concentration of Tm3+, cation elements that include at least an alkaline earth, phosphorus, and aluminum, and anion elements that include oxygen (O) and fluorine (F). The fluorine(F)/oxygen (O) ratio (F/(F+O)) for the fluorophosphate glass of the embodiments of the present invention can be in the range of about 0.5 to about 0.85. The fluorophosphate glass further can have an alkali metal concentration of 10 mole % or less to improve durability. The Tm-doped fluorophosphate glass can be incorporated into an amplifier or laser utilized in the 14xx nm wavelength region.
摘要:
A low temperature fluorophosphate glass useful for joining single-mode fluoride and silica optical fibers includes 5 to 7 mol % InF3, 20 to 35 mol % PbF2 and 57.5 to 75 mol % P2O5. An alkali for maintaining a low glass transition temperature can be included. Up to 25% (glass molar basis) of the P2O5 can be replaced by PbO.
