## Abstract A polarimetric multilongitudinal‐mode distributed Bragg reflector fiber laser sensor is proposed and experimentally demonstrated. We have theoretically analyzed the mode beat mechanism of this laser sensor, which is verified by the experimental observation, and its application in strain
Characteristics of the distributed Bragg reflector fiber laser sensor for lateral force measurement are investigated. The distributed Bragg reflector fiber laser operates in dual-polarization modes and converts the lateral force into a corresponding shift in the beat frequency generated by the fiber
## Abstract An active strain sensing system based on single‐longitudinal‐mode distributed Bragg reflector fiber laser is proposed and experimentally demonstrated. Owing to the short laser cavity length and birefringence‐induced mode splitting, the proposed laser in single‐longitudinal‐mode operatio
