High-power fiber laser materials: influence of fabrication methods and codopants on optical properties

In this contribution the influence of fabrication technique (solution doping, gas-phase doping) and the choice of suitable material systems (Al, P, Yb:SiO2 and Al, F, Yb:SiO2) for high power fiber laser materials on their optical properties is analyzed. The materials under analysis contain low amounts of codopants (Yb < 0.15 mol%, other
