Abstract
A doubly resonant short cavity Brillouin ring-laser actively stabilized with a wavelength locking system are employed as a low-RIN pump-probe source for Brillouin optical time-domain analysis (BOTDA) sensing. The developed high-stability narrow-linewidth laser scheme is compared to a long-cavity ring laser, showing the potential for enhanced temperature-strain resolutions.File in questo prodotto:
