| Summary: | We present a study of chalcogenide glass fiber lasers doped with
Dy3+, Pr3+ or Tb3+ that would operate in the mid-infrared wavelength range.
A set of chalcogenide glass samples doped with different concentrations of
rare earth ions is fabricated. The modeling parameters are directly extracted
from FTIR absorption measurements of the fabricated bulk glass samples
using Judd-Ofelt, Füchtbauer–Ladenburg theory and McCumber theory.
The modeling results show that, for all the dopants considered, an efficient
mid-infrared laser action is possible if optical losses are kept at the level of
1dB/m or below.
