“…The WDM for 1550 nm and 980 nm is used to combine and divide the light with different wavelength. The EDF is used as an active medium which can be pumped by a 980 nm diode laser and its signal wavelength ranges from 1520 to 1565 nm [ 17 ]. When light emitted from the pump source transmits through EDF, it will occur stimulated emission.…”

A review for optical fiber sensors based on fiber ring laser (FRL) demodulation technology is presented. The review focuses on the principles, main structures, and the sensing performances of different kinds of optical fiber sensors based on FRLs. First of all, the theory background of the sensors has been discussed. Secondly, four different types of sensors are described and compared, which includes Mach–Zehnder interferometer (MZI) typed sensors, Fabry–Perot interferometer (FPI) typed sensors, Sagnac typed sensors, and fiber Bragg grating (FBG) typed sensors. Typical studies and main properties of each type of sensors are presented. Thirdly, a comparison of different types of sensors are made. Finally, the existing problems and future research directions are pointed out and analyzed.

“…In the last decades, several research groups have employed different optical fiber structures as sensing heads in fiber laser sensors: tapers [27], multimode interference filters [28], and all fiber interferometers [29][30][31][32]; these elements improve the possibility of tuning a lasing mode. As a consequence, multiple parameters have been detected using fiber laser sensors: refractive index [33,34], curvature [35,36], strain [37][38][39], temperature [40][41][42][43][44], magnetic field [45,46], liquid level [27,47], torsion [48], rotation [49], gas concentration [29,50], gas pressure [51,52], relative humidity [32,53], and ultrasound [54]. In many of these works, the sensitivity reported by prior works was improved, and simultaneous detection of multiple parameters was also demonstrated.…”

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.

This work shows a study of pressure gas sensing using an optical fiber interferometer inside a gas cell; here, a thin-core fiber modal interferometer (TCFMI) is fabricated using two distinct types of fiber, a single-mode fiber (SMF model 1060XP) and thin-core fiber (TCF model 460 HP). This interferometric structure is set into a ring fiber laser with an ytterbium-doped fiber (YDF) pumped with a 980 nm laser diode. The TCFMI interference spectrum shows wavelength shifting and amplitude variations as the chamber pressure is altered in the range of 5 to 40 PSI; these changes control the ring fiber laser cavity response linearly and lead to good stability in its wavelength operation in a range of 30 nm. The proposed interferometer operates as a wavelength-selective filter in the fiber ring laser cavity. The single laser emission shows a side mode suppression ratio of 34.17 dB. The fiber ring laser is a reliable alternative for air pressure sensing applications.
