Abstract: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.
Yb-doped cladding-pumped fiber laser with linearly-polarized output emission was realized. To obtain linear-polarization operation we have applied Bragg grating written in the fiber with high birefringence as the input reflector. The polarization extinction ratio was of 17 dB. A maximum output power of 12 W was achieved with an efficiency slope of 69%. The laser linewidth was less than 0.1 nm even for maximum output power.
All-fiber Raman fiber source emitting at 1254 nm was realized. For the first time to pump Raman converter we have applied Yb:Bi pulsed fiber laser. The P-doped fiber was used as an active medium of the Raman converter. The conversion slope efficiency of 70% and the peak power of 12 W were observed.
