[94 km Brillouin distributed optical fiber sensors based on ultra-long fiber ring laser pumping].

Abstract

A novel optical amplification configuration based on ultra-long fiber laser with a ring cavity was proposed and applied to Brillouin optical time-domain analysis (BOTDA) sensing system, in order to extend the measurement distance significantly. The parameters used in the experiment were optimized, considering the main limitations of the setup, such as… (More)
