We experimentally demonstrate a multiwavelength Brillouin-erbium random fiber laser with a linear half-open cavity, by combining Rayleigh scattering with the reflection of a chirped fiber Bragg grating. The linear half-open cavity configuration is successful in obtaining multiwavelength random fiber laser with flattened output spectra, which is verified by both about 4.3 dB peak power difference between the first and fourth channel and inconspicuous peak power discrepancy between the odd and even Stokes lines. Up to five output channels with a spacing of about 0.088 nm, a linewidth of about 0.02 nm and optical signal-to-noise ratio over 15 dB have been obtained. © 1995-2012 IEEE.
