Abstract

Novel lanthano-alumino-silicate optical fibers doped with ytterbium (Yb) in a wide concentration range are obtained through the conventional modified chemical vapor deposition process and solution doping technique. The featuring fibers´ characteristics are determined, applying a routine that involves the spectroscopic, nonlinear-optical, and laser methods as well as photodarkening tests. Special attention is paid to address thoroughly the effect of concentration upon the fibers´ properties.
