Abstract

Highly phosphorus-doped (10–17 mol. % P2O5) low loss single-mode fibers have been developed. The results of the detailed investigation of an extremely simple and efficient 1.24. m phosphosilicate fiber-based Raman laser with Bragg gratings written directly in the fiber used are reported. The laser pumped by Nd fiber laser exhibits a quantum efficiency of 77%. 1.48-µm phosphosilicate fiber-based Raman laser with an output power of 1 W is developed.
