In this study, a fiber laser operating at 1015 nm was realized for the first time, confirming a new mechanism where 1D2 can be the upper energy level. The broad emission spectra of Pr3+-doped fibers were also utilized as new spectral sources.
To date, lasing in the visible to near-infrared wavelengths has been studied for praseodymium-doped fluoride fibers with the upper energy level of 3P0. In this Letter, a fiber laser operating at 1015 nm has been realized for the first time, to the best of our knowledge, which confirms a new mechanism where 1D2 can be the upper energy level. A maximum out-put power of 241 mW, with a slope efficiency of 30%, was achieved by using a 150-cm-long active fiber pumped at a maximum pump power of 823 mW. Furthermore, the broad emission spectra of Pr3+-doped fibers in the near-infrared band have been exploited as new, to the best of our knowl-edge, spectral sources. (c) 2022 Optica Publishing Group
