Abstract
A 974 nm laser diode(LD) pumped 1120 nm ytterbium(Yb)-doped fiber laser has been experimentally demonstrated, which will be subsequently used to pump 1178 nm Raman fiber laser based on stimulated Raman scattering(SRS) effect. The resonator composes a normal single-mode Yb-doped fiber and a pair of fiber Bragg gratings(FBG). The maximum output power of 8.4 mW is achieved when the launched pump power is 183.7 mW with an optical-to-optical conversion efficiency of 4.6 %. The central wavelength is 1120.93 nm with a linewidth as narrow as 0.02 nm.
