A low-noise Brillouin/erbium fiber laser module for optical sensing
We demonstrate a low-noise Brillouin/erbium fiber laser module. The size of the module is 143 mm×113 mm×30 mm. Its output power is 16 mW. Its phase noise at 1 kHz is -142 dB re rad/Hz<sup>1/2</sup> (normalized to 1 m optical path difference). This low-noise fiber laser module presents important applications in many highly coherent optical fiber sensing systems.
