Distributed feedback fiber laser hydrophones are small in size, high in sensitivity, easy to be reused into arrays and recycled, which has become an important technical path in the field of fiber optic hydrophones. In this paper, the probe package structures and application of distributed feedback fiber laser hydrophones are reviewed. According to the characteristics of package structures, three main package structures and their array applications are introduced, which are bending beam type, side compression type and axial tension or compression type. By analyzing the research indexes of main research institutions at home and abroad, the advantages and disadvantages of different package structures of distributed feedback fiber laser hydrophones are compared, and the future development of distributed feedback fiber laser hydrophones array is prospected.
