Fiber laser hydrophone as possible detector of UHE neutrinos

The possibility to use a single mode erbium-doped fiber laser as hydrophone for deep sea acoustic detection is considered. The high sensitivity of these sensors, their immunity from electromagnetic fields and their faculty to work at high environmental pressure, make them particularly suitable for a wide range of deep sea acoustic applications, and in particular as acoustic detectors in under-water telescopes for high-energy neutrinos.
