Abstract：

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.
