Near infrared broadband emission of bismuth-doped aluminophosphate glass.
Near infrared broadband emission characteristics of bismuth-doped aluminophosphate glass have been investigated. Broad infrared emissions peaking at 1210nm, 1173nm and 1300nm were observed when the glass was pumped by 405nm laser diode (LD), 514nm Ar+ laser and 808nm LD, respectively. The full widths at half maximum (FWHMs) are 235nm, 207nm and 300nm for the emissions at 1210nm, 1173nm and 1300...
متن کاملUltrabroad emission from a bismuth doped chalcogenide glass.
We report emission from a bismuth doped chalcogenide glass which is flattened, has a full width at half maximum (FWHM) of 600 nm, peaks at 1300 nm and covers the entire telecommunications window. At cryogenic temperatures the FWHM reaches 850 nm. The quantum efficiency and lifetime were as high as 32% and 175 mus, respectively. We also report two new bismuth emission bands at 2000 and 2600 nm. ...
متن کاملChalcogenide glass microsphere laser.
Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and ...
متن کاملBismuth-doped Silica Fiber Amplifier
To accommodate rapidly increasing quantities of information and communication, optical fiber transmission technology with high-speed high-capacity is demanded. The development of an optical gain medium and fiber amplifiers to cover the 1250~1650 nm region, which is the entire optical telecommunication windows of silica fiber, becomes an important issue for ultra-wide broadband optical communica...
متن کاملUpconversion emission of a Er3+-doped glass microsphere under 633 nm excitation
In this work, The TBS glass microspheres doped with Er3þ for morphology-dependent resonances of upconversion emission were designed. The glass sample components are 25TiO2–27BaCO3–8Ba(NO3)2–6ZnO2–9CaCO3–5H3BO3–10SiO2–7water glass-3Er2O3 (wt%), and the emission spectra of TBS glass and a TBS glass microsphere (about 48 mm in diameter) were measured under 633 nm excitation and discussed. The stro...
