Rare Earth Doped Fiber Lasers for Spectral Region about 2 Micrometers

Abstract

Previous fiber laser research was strictly targeted for high efficiency, economical and exceedingly thin‐disk lasers within beam quality parameters. Ytterbium doped silica fiber was the preferred fiber for most industrial applications. However, rest of rare earth doped active fibers were only demonstrated in basic principles via laboratory experiments, suggesting that many interesting solutions have yet to be studied. The purpose of this thesis is to develop methodology of key fiber laser components for wavelength range of 1.7 μm to 2.2 μm and to evaluate applications of these components to basic fiber lasers concepts further to explore and exploit their potential uses.
