Abstract

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.
