摘要: The authors report on the ability of Pr/sup 3+/-Yb/sup 3+/ codoped system to move pumping wavelength wavelengths shorter than 1.017 mu m. It was demonstrated that, by codoping Yb/sup with 3+/-doped fluoride fiber, amplifiers can be moved spectral range where effective done InGaAs laser diodes that have strained-layer quantum-well structures were developed as a source for Er/sup fiber amplifiers. extended down 0.93 >
