Laser fiber source implemented with a resonator Sagnac, for fiber optic acoustic sensor

摘要

In this work the authors present a simple laser source is implemented using erbium-doped fiber and a Sagnac fiber resonator to generate emission in the wavelength at 1550 nm. The pumping source this carried out with a erbium-doped fiber that serves from feeding to the Sagnac fiber resonator-a simple fiber ring resonator, this it generates a quite stable sign, This signal is regulated with a polarization controller, which allows to obtain at the output of the pumping source, a signal can be adjusted to the spectral width. Signal fed to the fiber optic acoustic sensor, with known characteristics.
