HYBRID BRILLOUIN ERBIUM FIBER LASER

We propose and demonstrate a novel hybrid Brillouin/erbium fiber laser that uses both Brillouin gain in single-mode optical fiber and gain i n erbium-doped fiber. The lasing frequency was accurately determined b y the Brillouin shift in single-mode optical fiber and was 10.35 GHz f rom the Brillouin pump. Large powers could be extracted because of inc orporation of erbium-doped fiber in the laser resonator. An output pow er of 10 mW was measured at a wavelength of 1532 nm.
