In this paper, an ultra-narrow linewidth hybrid Brillouin/thulium fiber laser (BTFL) was demonstrated. By optimizing the output coupling, pump scheme, fiber length and Brillouin pump power for the linewidth narrowing, 344-mW output power with a narrow linewidth of 0.93 kHz was obtained from the BTFL, in which the linewidth of Stokes light was suppressed more than 43 times compared with the 40 kHz linewidth of the Brillouin pump. Besides, the influences of output coupling and pump scheme on the power and linewidth behavior of a single-frequency BTFL were also experimentally investigated, and there exists a performance balance among linewidth narrowing, output power and SBS threshold. The output coupling exerted a significant influence on the BTFL performance. (C) 2020 Optical Society of America under the terms of the OSA Open Access Publishing AgreementNote
