Abstract
A numerical model that describes the operation behaviors and output characteristics of stable gain-switched Tm-doped fiber (Tm:fiber) lasers resonantly pumped at 1.56 mm is presented in this paper. Effects of some important laser parameters, such as repetition rates, pump power levels, transmission of the laser output coupler, fiber core sizes, fiber lengths, Tm concentrations, etc., on laser output were investigated. The model and simulating results were verified by preliminary experiments and good agreements have been achieved, suggesting that the model are useful for design and optimization of stable gain-switched Tm:fiber lasers at 2 mm wavelength region.
