Abstract
The measured spectroscopic properties of Pr3+- doped into sulfide and fluor ide hosts are used to model the gain efficiency of a 1300-nm Pr-doped fiber amplifier. It is found that excited-state absorption from the long-lived H -3(5) level in Pr3+-doped sulfide glass causes a significant degradation in performance, especially at wavelengths shorter than 1320 nm, Pr3+-doped fl uoride glass does not suffer significantly from this effect, although the m aximum gain is smaller in the fluoride glass.
