Novel dielectric nanoparticles (DNP) doped nano-engineered glass based optical fiber for fiber laser
We have developed the technology for making of dielectric nano-particles (DNP) doped nano-engineered glass based optical fibers. Two kinds of DNP containing silica glass based Yb2O3 doped fibers are made successfully through solution doping (SD) technique. One: Yb2O3 doped yttria-rich alumino-silica nano-particles based optical fiber developed during drawing of D-shaped low RI resin coated large mode area (LMA) optical fiber from the modified preform which annealed at 1450-1550°C for 3 hours under heating and cooling rates of 20ºC/min and other: Yb2O3 doped zirconia-germanium-alumino (ZGA) rich yttria-silica nano-particles based optical fibers developed during drawing of normal RI coated single mode optical fiber from the modified preform which annealed at 1000-1100°C for 3 hr under heating and cooling rates of 20°C/min. Fabrication of Yb2O3 doped yttria-rich alumino-silica nano-particles based D-shaped low RI coated large core optical fibers having core diameter around 20.0-30.0 micron was made. The size of DNP nano-particles was maintained within 5-10 nm under doping of 0.20 mole% of fluorine. The start fiber preforms are studied by means of EPMA, EDX, and electron diffraction analyses, revealing phase-separated nano-sized ytterbium-rich areas in their cores. There is a great need to engineer the composition as well as doping levels of different elements within the core glass during the preform making stages to generate phase-separated Yb2O3 doped DNP nano particles in the fiber. The matter concentrates on making of Yb2O3 doped DNP containing optical fibers along with material characterizations, study of spectroscopic properties, photo-darkening phenomena, and lasing characteristics. Such kind of nano-engineered glass based optical fibers shows good lasing efficiency with improved photodarkening (PD) phenomena compared to the standard silica glass based optical fibers.

Abstract

We have developed the technology for making of dielectric nano-particles (DNP) doped nano-engineered glass based optical fibers. Two kinds of DNP containing silica glass based Yb2O3 doped fibers are made successfully through solution doping (SD) technique. One: Yb2O3 doped yttria-rich alumino-silica nano-particles based optical fiber developed during drawing of D-shaped low RI resin coated large mode area (LMA) optical fiber from the modified preform which annealed at 1450-1550°C for 3 hours under heating and cooling rates of 20ºC/min and other: Yb2O3 doped zirconia-germanium-alumino (ZGA) rich yttria-silica nano-particles based optical fibers developed during drawing of normal RI coated single mode optical fiber from the modified preform which annealed at 1000-1100°C for 3 hr under heating and cooling rates of 20°C/min. Fabrication of Yb2O3 doped yttria-rich alumino-silica nano-particles based D-shaped low RI coated large core optical fibers having core diameter around 20.0-30.0 micron was made. The size of DNP nano-particles was maintained within 5-10 nm under doping of 0.20 mole% of fluorine. The start fiber preforms are studied by means of EPMA, EDX, and electron diffraction analyses, revealing phase-separated nano-sized ytterbium-rich areas in their cores. There is a great need to engineer the composition as well as doping levels of different elements within the core glass during the preform making stages to generate phase-separated Yb2O3 doped DNP nano particles in the fiber. The matter concentrates on making of Yb2O3 doped DNP containing optical fibers along with material characterizations, study of spectroscopic properties, photo-darkening phenomena, and lasing characteristics. Such kind of nano-engineered glass based optical fibers shows good lasing efficiency with improved photodarkening (PD) phenomena compared to the standard silica glass based optical fibers.
