A confined-doped ytterbium fibre with a 41 µm core diameter has been fabricated by direct nanoparticle deposition process. Near-diffraction-limited beam quality (M2∼1.3) was experimentally demonstrated from an amplified spontaneous emission source

We study the temperature of an Yb-doped large-mode-area (LMA) fiber during an accelerated photodarkening experiment. In these measurements, photodarkening is optically induced by IR irradiation (i.e. 915 nm) while the fiber temperature is measured by

Photodarkening is a detrimental phenomenon known to affect ytterbium doped fibers. Methods to study the spectral and temporal properties of the photodarkening induced loss were developed. The spectral shape of the photodarkening loss measured from mu

Accuracy at which population inversion in an ytterbium-doped fiber can be determined by modeling is studied. Here inversion refers to the percentage of ions excited to a higher energy level by the various optical fields. Knowledge of rare-earth ion i
