Abstract
A model description of photo darkening of ytterbium cw fiber lasers based on long term tested fiber lasers is presented. Photo darkening of Yb/Al co-doped silica fibres is found to saturate following prolonged exposure to pump and signal radiation. The observed slope efficiency of Al co-doping is compared with modeled slope efficiency of P co-doping.
