Yb-doped yttria–alumino–silicate nano-particles based optical fibers: Fabrication and characterization

Abstract An efficient method to fabricate transparent glass ceramic fibers containing in-situ grown Yb 3+ doped oxide nano-particles based on yttria–alumino–silicate glass is presented. These large-mode area Yb 3+ doped fibers having a core diameter around 25.0 μm were drawn by a proper control over the involved process parameters; by this, the size of nano-particles was maintained within 5–10 nm. The main spectroscopic and laser properties of the fabricated fibers along with the nano-structuration results are reported. These results reveal that the developed method offers new scopes for the contemporary Yb 3+ fiber based devices.
