Stable simultaneous multiwavelength lasing is demonstrated with a novel fiber‐ring laser incorporating a semiconductor optical amplifier. Band‐pass comb filtering is constructed in the ring cavity with the combination of a wideband Fabry–Perot comb filter and a bandpass filter. Ten lasing lines with a fixed wavelength spacing of 1.6 nm are implemented and the multiwavelength lasing ranges can be flexibly chosen. © 2004 Wiley Periodicals, Inc.
