Enhanced-performance fibre Brillouin ring laser for Brillouin sensing applications
2018
In this work we disclose a novel double resonant-cavity Brillouin ring-laser for Brillouin sensing employing wavelength locking. The tunable probe light exhibits a low RIN (~−145 dB/Hz) and a narrow pump-locked linewidth (~200 Hz), resulting in a stable BOTDA pump-probe source.(
