“…Besides, RDFB-FL present mode-less behavior, which is useful in multiwavelength and tunable laser sources [121][122][123][124][125] since the undesired mode competition or mode hoping are eliminated. Their ability to generate outstanding stable narrow-linewidth laser sources can be exploited in many sensing applications [140][141][142][143][144], being able to achieve high-resolution measurements [142]. In addition, RDFB-FLs can be internally modulated without frequency restrictions or self-mode-locking effects.…”

An overview of truly remote fiber optic sensors is presented in this work. It starts with a brief introduction of fiber optic sensor networks, showing their advantages and multiple applications. Then, the definition of truly remote networks is provided, and their main challenges discussed, such as increasing the sensing distance and the number of sensors interrogated. Several multiplexing techniques have been compared, such as wavelength, time and coherence division multiplexing. In relation to this, the most recent works showing multi wavelength fiber lasers for wavelength division multiplexing have been grouped and their versatility analyzed. Finally, recent and relevant truly remote fiber optic networks have been gathered and some of the most representative schemes explained in detail, comparing their multiplexing capability and the remoteness of the monitored sensors. Random distributed feedback fiber lasers form part of a number of these schemes, proving the suitability of this type of lasers for their use in ultra-long truly remote sensing applications.

“…The random fiber laser operating via Rayleigh scattering was first demonstrated in 2010 in a standard telecommunication fiber span, which provides both the randomly distributed Rayleigh feedback and the Raman gain [1,2] . With the intrinsic cavity-free configuration and "modeless" spectrum, random Raman fiber lasers (RRFLs) have unique properties and advantages such as high efficiency/high output power [3] , ultra-broad wavelength tunability [4][5][6] , and flat-amplitude multi-wavelength operation [7,8] . A number of important applications of RRFL have been explored, such as remote sensing [9] , speckle-free imaging [10] , and supercontinuum generation [11,12] .…”

In this Letter, we experimentally investigate fast temporal intensity dynamics and statistical properties of the claddingpumped Er/Yb co-doped random Rayleigh feedback fiber laser (EYRFL) for the first time, to the best of our knowledge. By using the optical spectral filtering method, strong and fast intensity fluctuations with the generation of extreme events are revealed at the output of EYRFL. The statistics of the intensity fluctuations strongly depends on the wavelength of the filtered radiation, and the intensity probability density function (PDF) with a heavy tail is observed in the far wings of the spectrum. We also find that the PDF of the intensity in the central part of the spectrum deviates from the exponential distribution and has the dependence on the laser operating regimes, which indicates some correlations among different frequency components exist in the EYRFL radiation and may play an important role in the random lasing spectrum stabilization process.

“…With the good laser performance and relative simplicity of implementation, RFLs have also been proved to be an important novel light source for optical communications [3,4], imaging [5][6][7][8], and high power applications [9][10][11][12][13]. In recent works, RFLs have been tailored to be multi-wavelength [14,15], wavelength tunable [16,17], narrow bandwidth [18,19], polarized output [20][21][22][23], high efficiency, and high output power [24][25][26][27].…”

In this paper, a cladding-pumped erbium-ytterbium co-doped random fiber laser (EYRFL) operating at 1550 nm with high power laser diode (LD) is proposed and experimentally demonstrated for the first time. The laser cavity includes a 5-m-long erbium-ytterbium co-doped fiber that serves as the gain medium, as well as a 2-km-long single-mode fiber (SMF) to provide random distributed feedback. As a result, stable 2.14 W of 1550 nm random lasing at 9.80 W of 976 nm LD pump power and a linear output with the slope efficiency as 22.7 % are generated. This simple and novel random fiber laser could provide a promising way to develop high power 1.5 μm light sources.
