All polarization maintaining Brillouin erbium-doped fiber laser with narrow linewidth and stable single longitudinal mode

International Academic Conference on Optics and Photonics
A single-longitudinal-mode (SLM) narrow-linewidth Brillouin erbium-doped fiber laser (BEFL) is proposed and demonstrated experimentally. The erbium-doped fiber (EDF) is employed to act as both the linear gain and Brillouin gain medium, which makes it ...
