• 論文の詳細を見る

• Fundamentals and development of PDFAs are described. Spectroscopic data of Pr^<3+> in a fluoride glass are presented with a view to understanding the performance of PDFA. An amplification mechanism model which explains PDFA performance is established. On the basis of the model pump schemes which efficiently extract the potential in Pr^<3+>-doped fluoride fiber are discussed in order to construct amplifier modules. Gain characteristics of Pr^<3+>-doped fluoride fibers are clarified. Codoping effect on pump wavelength extension is investigated. LD-pumped PDFA construction and performance are described. PDFAs are shown to be attractive device to upgrade the performance of optical systems at 1.3 μm. Furthermore future approaches to PDFA research are discussed.
