“…[57,168] However, the wavelength channel number and the spacing of the FBG-based multi-wavelength RFLs are hard to change. Hence, fiber interferometry, such as Fabry-Perot interferometer, [147] Mach-Zehnder interferometer, [184] and Sagnac interferometry, [185][186][187] could be a better option for multiwavelength random fiber lasing generation. For example, the SMF-MMF-SMF-constructed multimode interference filter was added to the reflector of an RRFL to generate cascaded multiwavelength lasing emission.…”

Random fiber lasers (RFLs), a new variety of random lasers, have become a vigorous research spot over the past decades. RFLs possess superiorities in efficiency, structural flexibility, directionality, cost, etc. Particularly, RFLs are discovered to be good platforms for the construction of various forms of high‐performance lasers. Herein, recent progress in the spectral manipulation of RFLs and the applications of spectral‐tailored RFLs are reviewed. Both theoretical and experimental investigations of the unique spectral properties of RFLs up to now are presented. The superior wavelength flexibility of RFLs which can achieve any desired lasing wavelength in the 1–2.1 µm band is highlighted. Via spectral manipulation, RFLs have shown the capability of high‐spectral‐purity, narrow‐bandwidth, and multi‐wavelength output. Furthermore, the RFLs featuring unique spectral properties can lead to various promising applications, which are concisely summarized, including optical fiber communication, optical fiber sensing, imaging, supercontinuum generation, nonlinear‐frequency conversion, mid‐infrared lasing pump sources, and laser‐driven inertial confinement fusion motivation. The challenges and prospects for RFLs are also discussed.

“…Ma et al reported a quasi mode-locked RFL based on graphene saturable absorber [24]. Based on multimode interference effect spectrum clipping, Wu et al demonstrated a spectrum clipping scheme a spectrum tailoring scheme of RFL by changing the filter length [25]. Hu et al realized mode-locked laser pulses by passive mode locking with selectable repetition rate [26], and employed a FBG as one reflector of the cavity and achieved the locking wavelength range of 0.5 nm from 1552.3 to 1552.7 nm, with the wavelength and power fluctuation less than 0.01% and 4%, respectively [27].…”

A highly-stable and effective Er-doped random fiber laser is proposed and experimentally demonstrated based on external optical injection locking technology. By adjusting the optical injected wavelength, the lasing wavelength can be selected precisely and emitted separately within the spectral bandwidth of 1555.5 nm to 1563.5 nm. The wavelength and output power fluctuation are less than 0.004% and 2.9%, respectively, indicating that optical injection locking of the random fiber laser is quite stable over a long time. The optical injection locking technology is used in the half-open cavity incoherent RFL systems based on the random distributed Rayleigh scattering scheme, which provides an effective method to control or select the wavelength emission with high stability in a random fiber laser.

“…Measurement systems that involve fiber lasers have the advantages of an extensive tuning range and high coupling efficiency. However, fiber lasers are usually expensive and have a slow tuning rate which is restricted by the core component, such as tunable fiber filters [30]. The vertical cavity surface emitting laser (VCSEL) and external cavity semiconductor laser (ECSL) comprise micromechanical components, which leads to poor mechanical resistance, limiting their applications [31].…”

In this paper, a cost-effective and miniaturized instrument is proposed, which is based on a tunable modulated grating Y-branch (MG-Y) laser for rapid temperature measurement using a Fabry-Perot interferometer (FPI) sensor. The FPI sensor with a 1 463-µm cavity length is a short segment of a capillary tube sandwiched by two sections of single-mode fibers (SMFs). This system has a broad tunable range (1 527 nm–1 567 nm) with a wavelength interval of 8 pm and a tuning rate of 100 Hz. Temperature sensing experiments are carried out to investigate the performance of the system by demodulating the absolute cavity length of the FPI sensor using a cross-correlation algorithm. Experimental results show that the sensor can reach the response time as short as 94 ms with the sensitivity of 802 pm/°C. Benefiting from the homemade and integrated essential electrical circuits, the entire system has the small size, low cost, and practical application potential to be used in the harsh environment for rapid temperature measurement.
