title: Composite cavity fiber laser sensors based on weak feedback.
abstract: A novel composite cavity optical fiber laser (CCFL) sensor, based on weak feedback of the optical fiber end face, is proved theoretically and experimentally. The application of the vibration measurement based on the CCFL sensor is demonstrated to prove its feasibility.
