Rare-earth-doped chalcogenide glass for mid- and long-wave IR fiber lasers

Rare earth doped chalcogenide glass fibers have been developed at NRL. Spectroscopic investigation of these glasses and fibers show that they possess strong and efficient mid-IR and long-wave IR emissions suitable for fiber lasers in these wavelength regions. Small fiber sources based on these emission lines have been developed and can be used as bright IR sources for characterizing focal planes.
