Abstract
We demonstrate a simple DFB fiber laser hydrophone and its demodulation is realized by a simple intensity based scheme. DFB fiber lasers with and without packaging structures are used as hydrophones and their measurement results are given. The frequency response of the DFB fiber laser based hydrophone is measured in an anechoic water pool. The feasibility of the hydrophone is proved by a referenced B&K8014 hydrophone.
