ABSTRACT:
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 Al(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 well 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.
