ABSTRACT
Pr3+-doped fluorotellurite glass fibers (PDFTFs) were fabricated by using a rod-in-tube method. By using a 976/1400â
nm dual-wavelength upconversion pump technique, an intense emission at 605â
nm was obtained from a 6â
cm long PDFTF, which was attributed to the transition 1D2 â 3H4 of Pr3+ ions. With an increase in power of the 1400â
nm laser from â¼34 to â¼136â
mW, the spectral bandwidth of the 605â
nm emission decreased and the intensity of the 605â
nm emission increased monotonically, indicating the generation of 605â
nm amplified spontaneous emission (ASE). To the best of our knowledge, this is the first report of 605â
nm ASE in PDFTFs. Our results showed that PDFTFs had the potential for constructing red fiber lasers and amplifiers.
