Paper Abstract

The direct interaction of an acoustic field with a planar fiber laser cantilever in a fluid is investigated. It is shown that a sensor based on this transduction mechanism responds to acoustic particle velocity with a responsivity around 5×104 Hz/Pa yielding a resolution of 1.6 mPa/Hz1/2 at 100Hz, which is adequate for many underwater acoustic applications. Issues related to developing a practical, miniaturized sensor are discussed.
