Mid-infrared photoluminescence in small-core fiber of praseodymium-ion doped selenide-based chalcogenide glass (2015)
Journal Article
Tang, Z., Furniss, D., Fay, M., Sakr, H., Sójka, L., Neate, N., …Seddon, A. B. (2015). Mid-infrared photoluminescence in small-core fiber of praseodymium-ion doped selenide-based chalcogenide glass. Optical Materials Express, 5(4), 870-886. https://doi.org/10.1364/OME.5.000870

© 2015 Optical Society of America. Rare earth (RE)-ion doped chalcogenide glasses are attractive for mid-infrared (MIR) fiber lasers for operation >4 μm. Our prior modeling suggests that praseodymium (Pr) is a suitable RE-ion dopant for realizing a s...

Gallium (Ga) helps solubilize rare-earth ions in chalcogenide glasses, but has been found to form the dominant crystallizing selenide phase in bulk glass in our previous work. Here, the crystallization behavior is compared of as-annealed 0–3000 ppmw...
