Abstract

Summary form only given. We have recently demonstrated order-of-magnitude emission lifetime (quantum yield) improvements in several Pr-doped chlorides. Dy³⁺ doped sulfide glasses have recently been proposed as 1300-nm amplifiers. Pr³⁺ ions are difficult to pump directly but Dy³⁺ possesses several strong candidate pump transitions. Spectroscopic characterization of various Dy³⁺-doped chlorides showed that several possess useful 1300-nm emission bands, and absorption and emission spectra of Dy³⁺:LaCl₃ are shown.
