Abstract

Numerical simulations of ${{\rm Dy}^{3 +}}$-doped aluminosilicate fiber lasers for yellow light emission are presented. The $^4{{\rm F}_{9/2}}\;{\to ^6}{{\rm H}_{13/2}}$ laser transition emitting at approximately 580 nm has been developed experimentally with 445 nm diode pumping and shows promise for higher output power in both silicate and in particular fluoride glass hosts. In this report, we focus on accumulating the published spectroscopic data in order to quantify cross relaxation (CR) in each of these hosts and use it to estimate its role in the laser dynamics. The model involves calculation of the branching ratios, and radiative and nonradiative decay rates and compares well with reported experimental results. We show the important role of the background losses on previous laser performance and the relatively strong increase in the laser threshold as a result of CR despite the moderately low ${{\rm Dy}^{3 +}}$ concentrations that have been experimentally tested.
