abstract

A multi-longitudinal-mode fiber laser sensor is proposed and experimentally demonstrated base on beat frequency demodulation method. A novel laser cavity is formed by a FBG, a section of erbium-doped fiber and a broadband reflector. The proposed laser sensor has ultra-stable frequency information due to self-phase matching of FBG, and high signal to noise ratio.
