✦ Synopsis

We have realized ytterbium fiber laser emitting at
1160 nm. To avoid a competition with a spontaneous lasing at
shorter wavelengths we pumped laser into the core at wavelength of
1070 nm. Cladding pumped Yb-laser was used as a pump source. Also,
the active fiber was heated up to 70°C to increase the
absorption of the pump power and suppress the spontaneous
emission. The lasing efficiency slope of 45% was measured. A
maximum output power of 3.2 W was achieved.

We report experimental results showing novel features in photo-darkening and photo-bleaching of a heavily-doped Ytterbium silica fiber exposed to in-core 977-nm and 543-nm irradiation. It is shown that pumping of the fiber at the resonant 977-nm wavelength leads to an increase of absorption in the s
