Pr3+- and Nd3+-doped glasses are the most promising candidates for fiber amplifiers in the 1300-nm telecommunication window, but each has serious drawbacks. Using a quantitative numerical model and measured cross sections, we have examined the practical limits of performance for Pr3+-doped fiber amplifiers (PDFAs) in small-signal and power amplifier applications. A comparison has been made between power PDFAs and Nd3+-doped fiber amplifiers (NDFAs). In general, only PDFAs provide gain over the complete wavelength range of interest. NDFAs are expected to have higher efficiencies if the short wavelength amplified spontaneous emission is suppressed and operation is limited to the long wavelength side of the 1300-nm window. Even when potential improvements are considered, the performance of PDFAs and NDFAs does not approach that of Er3+- doped fiber amplifiers.
