Self-mixing sensing technique can be used for measuring distances, displacements, velocities and vibration. In this paper, for good sensitivity vibration measurement system, self-mixing vibrator using an all-fiberized configuration Er3+eYb3+ Distributed Bragg Reflector (EYDBR) laser is proposed and investigated for the first time. Results obtained demonstrate that all-fiberized configuration EYDBR laser present a powerful tool for the advancement of self-mixing vibration sensor and provide a potential remote measurement of the vibration compared with the optical feedback in other traditional fiber lasers.
