Gyroscopes merit an undeniable role in inertial navigation systems, geodesy and seismology. By employing the optical Sagnac effect, ring laser gyroscopes provide exceptionally accurate measurements of even ultraslow angular velocity with a resolution up to 10−11 rad/s. With the recent advancement of ultrafast fibre lasers and, particularly, enabling effective bidirectional generation, their applications have been expanded to the areas of dual-comb spectroscopy and gyroscopy. Exceptional compactness, maintenance-free operation and rather low cost make ultrafast fibre lasers attractive for sensing applications. Remarkably, laser gyroscope operation in the ultrashort pulse generation regime presents a promising approach for eliminating sensing limitations caused by the synchronisation of counter-propagating channels, the most critical of which is frequency lock-in. In this work, we overview the fundamentals of gyroscopic sensing and ultrafast fibre lasers to bridge the gap between tools development and their real-world applications. This article provides a historical outline, highlights the most recent advancements and discusses perspectives for the expanding field of ultrafast fibre laser gyroscopes. We acknowledge the bottlenecks and deficiencies of the presented ultrafast laser gyroscope concepts due to intrinsic physical effects or currently available measurement methodology. Finally, the current work outlines solutions for further ultrafast laser technology development to translate to future commercial gyroscopes.

“…Moreover, rotation sensitivity turns out to be irrespective of the coil numbers of laser gyroscope as it is experimentally observed for the four-coil Gyro#2. This is one of the principal differences between a pure ring laser gyroscope (R-FOG) and a laser gyroscope with a passive Sagnac loop as a rotation sensor inserted into the laser cavity [31,32].…”

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.

“…A few decades later, Erbium optical fiber amplifiers opened the possibility of new sensing technologies [4,5]. The next decade, the fiber laser sensor emerged as a sensing alternative based on its tuning capability [6][7][8][9][10][11]. This feature offers a simple and not intricated demodulation process.…”

Fiber laser sensors have been present for almost four decades as versatile sensing devices with a simple demodulation process, high sensitivity, and competitive resolution. This work discusses the most representative fiber laser sensor configurations employed for detecting critical parameters such as temperature, refractive index, and strain. However, essential information about other interesting parameters that have been measured is considered in this manuscript. Concurrently, the sensing elements and principle operation are described. Furthermore, these configurations are analyzed in terms of their principle of operation, sensitivity, gain medium, and wavelength operation range. According to the literature reviewed, fiber laser sensors offer the possibility of new interrogation techniques and simultaneous, independent detection. Considering interferometric fiber sensors, the fiber laser sensors offer high brightness, good output power, and high resolution. As a result, it is demonstrated that fiber laser sensors are a robust alternative for multiple sensing applications.
