A noise-like pulsed Raman fiber laser using graphene oxide saturable absorber is reported, which adopts the all-fiber double-ring configuration, comprised by an Er-doped fiber resonator and a Raman fiber resonator. The Raman gain fiber is a 700 m commercial silicon-based high nonlinear fiber. When the pump power of the diode laser is 4.16 W, the Raman fiber laser generates stable 500 ns pulse trains at 250 kHz repetition rate. The central wavelength is 1690.2 nm and the radio of signal to noise is 53 dB.
