摘要：

A novel multiwavelength Brillouin-erbium fiber laser (MW-BEFL) based on the feedback fiber loop (FFL) is proposed. The main single pass ring is constructed by an optical circulator and a 50 m single mode fiber (SMF). In order to guarantee the single longitudinal mode operation of each Stokes waves and anti-Stokes waves, the FFL is configured with a 10 m SMF of traditional Brillouin-fiber laser. The system is enclosed in temperature control system so that environment disturbance is reduced. 45 dB sidemode suppression and 3.23 kHz linewidth of the first-order Stokes wave are measured by delay interference method. Through the cascaded stimulated Brillouin scattering (SBS) and degenerate four-wave mixing (FWM) process, the laser can be freely and steadily tuned in 50 nm range from 1525 nm to 1575 nm with 0.084 nm wavelength spacing.
