“…Many studies have been carried out to enhance the already promising inherent features of RDFB-FL, for instance, the optimization of the output power [104][105][106][107], relative intensity noise transfer [108,109]and thermal noise [110]. In addition, their spectral and statistical properties have been analyzed in [111][112][113] and a variety of configurations have been proposed implementing polarized pump or linearlypolarized outputs [114][115][116][117], mixing different fibers in the gain media [118], short cavities [119,120] and tunable [121], multi-wavelength [57,[122][123][124][125] or super-continuum output [126,127]. Finally, RDFB-FL schemes allow combining the traditionally employed Raman amplification with other amplification mechanisms such as Erbium.…”

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.

Compared with traditional uniform fibers, tapered fiber has numerous unique advantages, such as larger mode area, higher pump absorption, suppression to nonlinear effects, and maintaining good beam quality. In this manuscript, we have constructed an all-fiberized fiber amplifier which is based on a piece of ytterbium-doped tapered double-clad fiber (T-DCF). The fiber amplifier is operated under continuous wave (CW) regime at 1080 nm wavelength. The $M^{2}$ factor of the amplifier at 1.39 kW output power is ${\sim}1.8$. The maximum output power of the system reached 1.47 kW, which, to the best of our knowledge, is the highest output power of long tapered fiber based fiber laser system. Our result successfully verifies the potential of power scalability and all-fiberized capability of long tapered fiber, and the performance of our system can be further enhanced by fiber design optimization.

“…As a result, RRFLs have found applications in many fields, such as fiber optical sensing, pumping mid infrared laser and spectroscopic monitoring [2][3][4]. In previous studies, RRFLs with narrow linewidth, polarized output, cascaded generation, power scaling and pulsed operation have been realized [5][6][7][8][9][10][11].…”

An up to 8th order cascaded Raman random fiber laser with high spectral purity is achieved with the pumping of a narrow linewidth amplified spontaneous emission source. The spectral purity is over 90% for all the 8 Stokes orders. The highest output power is 6.9 W at 1691.6 nm with an optical conversion efficiency of 21% from 1062.0 nm. As a comparison, with conventional FBG-based fiber oscillator as pump source, only 47% spectral purity is achieved at 8th order. The temporal stability of the pump laser is proved to play a key role, because the time fluctuation of pump laser is transferred directly to Raman outputs and results in power distribution among different Stokes orders.
