1.06-microm all-fiber gyroscope with noise subtraction.
An all-fiber gyroscope that uses a 1.06-microm multicore Nd-doped fiber source pumped by a laser-diode array is demonstrated. Intensity noise subtraction is used to reduce the excess noise that arises from a source bandwidth limitation. The random walk coefficient is improved by a factor of 3, to 2.5 x 10(-4) deg radicalh (1-km fiber, 16-cm radius).
