Modeling of rare-earth-doped glass devices and optical parameter indirect evaluation

The model of rare-earth-doped optical devices based on the rate equations and the power propagation equations can be employed for both the feasibility investigation of innovative challenging devices and the recovering, via an indirect approach, of the rare earth spectroscopic parameters. In this review, different and novel examples of rare-earth-doped device refinements as well as the evaluation of unknown optical parameters are reported. The investigated cases are obtained starting from developed models and computer codes illustrated in recent literature and from measured performance of lasers and amplifiers.
