We experimentally demonstrate a ring‐cavity, single‐wavelength Brillouin‐Raman fiber laser. An 11‐km long dispersion compensating fiber was used as the medium for the Raman as well as the Brillouin amplification. A threshold power of 27 mW was recorded to get the Brillouin‐Stokes line at 1455 nm pump wavelength. At an injected Brillouin pump power of 2 mW, while the Raman pump unit was fixed at a power of 296 mW, the single‐wavelength Brillouin‐Raman fiber laser can be tuned from 1520 nm to 1580 nm without any self‐lasing cavity modes in the laser system. The Brillouin‐Stokes line has a 3‐dB power fluctuation within 26 nm from 1542 nm to 1568 nm. (© 2010 by Astro Ltd., Published exclusively by WILEY‐VCH Verlag GmbH & Co. KGaA)
