摘要

A widely tunable multiwavelength single-longitudinal-mode fiber laser based on Rayleigh and Brillouin scattering effects is proposed and experimentally demonstrated. The amplified Rayleigh backscattering of seed light serves as the original Brillouin pump while the Rayleigh and Brillouin scattering in the single mode fiber provide randomly distributed feedback. When the seed light wavelength varies in C-band with the power of -8 dBm, the fiber laser can generate more than nine lasing lines with narrow linewidth and their maximum power fluctuation is less than 2.4 dB. The lasing lines are stable, rigidly separated by 10.852 GHz.
