A stabilized fiber laser for low frequency, high resolution sensing

A stabilized fiber laser is presented for low frequency, sensing applications. Suppression of noise to 15 fepsiv/radicHz (2 Hz/radicHz) is demonstrated at 60 Hz. For a 20 mm sensor, displacement sensitivity of 0.3 fm/radicHz is expected.
