Paper Abstract
A fiber laser hydrophone (FLH) based on a flat diaphragm and an L shaped lever is presented. This hydrophone uses an
L shaped lever to transfer the acoustic pressure induced defection of the flat diaphragm to the axial elongation of the
fiber laser. The curve where the L shaped lever contacts the diaphragm is a segment of an Archimedes spiral, which is
used to enhance the responsivity. To compensate the hydrostatic pressure, a capillary tube is fixed at the end of the
hydrophone. Both theoretical and experimental investigations are presented in this paper. The result shows that the
proposed design has a high sensitivity of a flat frequency response below 1 kHz.
