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