Yellow laser performance of Dy^3+ in co-doped Dy,Tb:LiLuF_4

Co-lasing in an electrically tunable erbium-doped fiber laser

Future fiber optic communications systems will utilize wavelength division mutliplexing as a means of transmitting more information over the same number of fibers. A single source capable of generating multiple frequencies simultaneously would be an attractive option for such systems. We report here on an all-fiber, dual-frequency, colasing, widely tunable laser source with the potential for mu...

Crystal Growth and Luminescence Properties of Dy3+ and Ge4+ Co-Doped Bi4Si3O12 Single Crystals for High Power Warm White LED

Φ1 inch Dy3+ and Ge4+ co-doped bismuth silicate (Bi4Si3O12, BSO) single crystals with the length of 80–100 mm were successfully grown by Bridgman method. They are transparent, free of cracks and inclusions. The white residual at the top parts of BSO crystals disappears with co-doping 1 mol% Dy3+ and more than 3 mol% Ge4+. The FWHM values of X-ray rocking curves shows 1%Dy,3%Ge:BSO crystal posse...

Magnetic Properties of Fe Doped, Co Doped, and Fe+Co Co-Doped ZnO

The structural, electronic and magnetic properties of Zn0.95Co0.05O, Zn0.95Fe0.05O and Zn0.90Fe0.05Co0.05O nanoparticles prepared by a sol-gel method are presented and discussed. Xray diffraction and optical analysis indicated that high spin Co ions substitute for the Zn ions in tetrahedral sites. Fe Mössbauer spectroscopy showed the presence of isolated paramagnetic Fe ions in both Fe doped an...

Thermoelectric performance of co-doped SnTe with resonant levels

C-band single-longitudinal mode lanthanum co-doped bismuth based erbium doped fiber ring laser.

We propose and demonstrate a stable, tunable and narrow linewidth C-band lanthanum co-doped bismuth based erbium doped fiber (EDF) ring laser with single longitudinal mode (SLM) operation. A free space thin film filter acts as a wavelength discriminative component selecting a few oscillating modes while a Lyot filter formed by a polarization maintaining (PM) fiber and a linear polarizer further...
