We report an increased number of stokes when used with a band‐pass filter in multiwavelength Brillouin erbium‐doped fiber laser (BEFL). A total of 15 Stokes were achieved as compared with seven in a system without the band‐pass filter. The efficiency of generating Brillouin Stokes improved due to the suppression of out‐of‐band amplified spontaneous emission in the BEFL. The band‐pass filter provides a specific range of lasing window that coincide with the Brillouin pump signal. The flatness of the Brillouin stokes is also improved in the proposed design. © 2004 Wiley Periodicals, Inc.
