Abstract

We present results of the research and development of the CW medium-power fiber lasers emitting in a range of 1-2 μm. Realized light sources are based on the application of rare-earth doped fibers and Raman converters pumped by semiconductor sources. A combination of the fiber lasers emitting at different wavelengths with Raman converters based on germanium or/and phosphorous fibers allows one to build a laser source emitting at any wavelength of near IR range. The reached quality of the fabricated fibers and optimization of reflecting Bragg gratings allowed us to demonstrate fiber lasers with a quantum efficiency closed to 90%. The fabricated lasers were used for a realization of Raman converters emitting at the various wavelengths.
