Abstract
The optical amplification characteristics in a Pr/sup 3+/-doped fluoride fiber have been demonstrated. The amplification band in a Pr/sup 3+/-doped fluoride fiber fully covers the 1.3 mu m telecommunication window, and a practical optical gain value of over 13 dB was obtained. Moreover, a saturation power of +9 dBm was attained. If the problems of pumping efficiency and wavelength are solved, Pr/sup 3+/-doped fluoride fiber will become available for 1.3 mu m booster amplifiers.Keywords
