title: Tunable random distributed feedback fiber laser operating at 1 μm.
abstract: A tunable random distributed feedback (RDFB) fiber laser operating at 1 μm is presented, which consists of a piece of ytterbium-doped fiber, a manual tunable filter and a 1-km-long single-mode fiber that provides RDFB. The wavelength of the RDFB fiber laser can be tuned continuously from 1040 to 1090 nm with a linewidth of about 0.4 nm. Power output maintains good flatness in the 50 nm tuning range, with fluctuations within 1 dB. It is the first reported tunable RDFB fiber laser working at 1 μm as far as we know.
