(2016) Numerical modeling of lathanide-ion doped fibre lasers operating within mid-infrared wavelength region. In: 18th International Conference on Transparent Optical Networks, 10-14 July 2016, Trento, Italy.
We discuss the numerical modelling of lanthanide-ion doped chalcogenide glass fibre lasers for operation in the mid-infrared wavelength region. We extract the modelling parameters from emission and absorption measurements using Judd-Ofelt and McCumber theory. Numerical algorithms are developed based on the experimentally extracted fibre parameters. The simulation results predict lasing with slope efficiency of at least 20 % provided, that the fibre loss can be kept at the level of 1 dB/m or less.
