Abstract

In this work we describe the development of a compact all-fiber pulsed light source composed by a fiber-Bragg-grating-based distributed-feedback fiber laser. We demonstrate that the temporal and spectral characteristics of this fiber laser are suitable as light source for Brillouin back-scattering sensors. Using a 10 km fiber spool, we have measured the Stokes and anti-Stokes processes at different pump powers and they were clearly discernible around the central (Rayleigh backscattering) peak at the appropriate wavelength shift (88 pm at room temperature). Our results indicate that this compact all-fiber source is a good alternative for Brillouin sensor applications.
