Abstract
An analytical model of holmium-doped fiber laser is proposed and verified experimentally. The model is based on a two-level model, assumes only transitions between levels 5I8 and 5I7 of the Ho3+ ion in silica, and enables to express the threshold pump power and laser slope efficiency in a closed form. The effect of intrinsic losses is modeled by a physically motivated semi-empirical formula. The model is compared with a numerical one and its application limits are discussed.
