摘　　要：We demonstrate a multi-wavelength Brillouin-erbium fiber laser(BEFL)with narrow linewidth and tunable wavelength interval using dual-wavelength Brillouin pumping.The generation of multi-wavelength output in BEFL is based on the combination of stimulated Brillouin scattering(SBS)and four-wave mixing(FWM)effect in a fiber cavity.The tunable wavelength interval is determined by the artificially controlled wavelength interval of the pumping lasers.The BEFL could compress a 1 MHz pump laser to a 340 Hz Brillouin Stokes laser,which proves the BEFL has excellent capability of linewidth compression.An erbium-doped fiber pumped by 980 nm laser is inserted into the cavity to further amplify the Brillouin laser.The wideband multi-wavelength BEFL covering over 50 nm is successfully generated when the 980 nm pump power is 400 mW.These features of multi-wavelength BEFL provide an effective method for optical communication systems and optical fiber sensing.
