| Abstract: | The experimentally obtained luminescence characteristics of a praseodymium (Pr $^{3+})$ doped chalcogenide glass fiber are studied numerically using a rate equation approach. The numerical model includes both the radiative and non-radiative transition paths whilst it neglects the up-conversion processes. Photoluminescence spectra at mid-infrared wavelengths ranging from 3.5 to 6 ${\upmu }$ m were obtained by using two pump wavelengths: 1.55 and 1.94 ${\upmu }$ m. A good agreement between the experiment and theory is obtained for the photoluminescence decay profiles. |
