Abstract
In this paper we report our investigation on the lifetime reduction in ytterbium doped aluminosilicate fibers due to the pump induced photodarkening (PD). We show a linear correlation between equilibrium lifetime reduction and equilibrium losses due to PD and a squared-law dependence between lifetime reduction at equilibrium and dopant concentration (wt%). Finally, we did not observe interplay between PD and quenching effect. The quantitative analysis carried out allows to determine the photodarkening quenching term in the laser rate equations system to properly model laser device.
