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...
The presentation gives an account of recent developments in the modelling of chalcogenide glass based lanthanide doped fibre lasers for the mid-infra-red (MIR) wavelength range. The particular lanthanide elements considered include dysprosium, praseodymium and terbium. Both classical 3 level lasing systems and cascade lasing systems are considered, and their properties compared. Steady state and pulsed...
