“…It should be stressed that since a scale factor itself is a dimensionless value, a multiple of π/180 is needed for an adequate comparison with experimentally measured rotation sensitivity values expressed in (Hz/(deg s −1 )). Moreover, the inverse dependence of S on refractive index n was previously obtained for fiber laser gyroscopes with a semiconductor optical amplifier (SOA) as an active media [29,30].…”

We report a study on the gyroscopic effect in a bidirectional ultra-short pulse erbium-doped all-fiber ring soliton laser hybridly mode-locked with co-action of single-walled carbon nanotubes and nonlinear polarization evolution introduced by a short-segment polarizing fiber. We directly compare two gyroscopes with different scale factor values and coil numbers by studying important gyroscopic characteristics such as rotation sensitivity, dead bandwidth and beat-note frequency stability. The detected angular velocity ranged from 0.12 deg s −1 to 360 deg s −1 , while the highest rotation sensitivity reached 7 kHz/(deg s −1 ) for a 0.79 m 2 single-coil ring gyroscope, which was in agreement with the calculated scale factor value. The gyroscope dead band with an upper limit of ≈5.15 deg s −1 corresponding to the lowest beat-note frequency of ≈15 kHz was detected during clockwise rotation of the turntable. The highest gyroscope resolution of R ~ 0.01 deg s −1 = 38 deg h −1 was estimated on the basis of bias point drift measurements.

“…The laser emission was multimode, as a result of which the small signal in the form of beats could be measured only at rather high rotation velocities. The studies were continued, but the sensitivity could be increased only up to 1 deg s -1 [3].…”
