“…An extremely flat tuning curve over the whole gain spectrum of the laser was demonstrated in this very simple configuration. Further works on tunable random DFB fiber lasers include [50,51]. In [52], tunability of a random fiber laser was demonstrated by using long period fiber Bragg gratings.…”

Doc. ID 239686)Random fiber lasers blend together attractive features of traditional random lasers, such as low cost and simplicity of fabrication, with high-performance characteristics of conventional fiber lasers, such as good directionality and high efficiency. Low coherence of random lasers is important for speckle-free imaging applications. The random fiber laser with distributed feedback proposed in 2010 led to a quickly developing class of light sources that utilize inherent optical fiber disorder in the form of the Rayleigh scattering and distributed Raman gain. The random fiber laser is an interesting and practically important example of a photonic device based on exploitation of optical medium disorder. We provide an overview of recent advances in this field, including high-power and high-efficiency generation, spectral and statistical properties of random fiber lasers, nonlinear kinetic theory of such systems, and emerging applications in telecommunications and distributed sensing.

Tailoring of the output laser spectral characteristics of an Erbium‐doped fiber laser (EDFL) by the intra‐cavity inscription of long‐period fiber gratings (LPFGs) is experimentally demonstrated. The intra‐cavity fabrication allows the accurate positioning of the LPFG notch bands in order to tailor the laser wavelength and at the same time suppress the side modes on the output laser spectrum. The red tail of the LPFG notch band is used as an edge filter to modify the gain spectrum, since its shape or slope is modified as the LPFG strength grows. As few as three periods are enough to tailor the laser wavelengths to a single laser line operation, with a side mode suppression ratio (SMSR) of 34.2 dB; while at six periods 37.79 dB of SMSR in a dual wavelength operation is demonstrated. © 2016 Wiley Periodicals, Inc.

“…Due to these advantages, attentions have been paid to their applications in fiber-optic sensing and communication [3]- [5]. Also, various aspects of RFL have been studied: RFL has been designed to be narrow bandwidth [6], multiwavelength [7], [8] wavelength-tunable [9], Manuscript high power [10]- [12] and generating high order Stokes waves [13], [14]. Besides, the concept of RFL can be further developed by using Brillouin gain instead of Raman gain [15].…”

In this letter, we numerically study and experimentally achieve a low-threshold, high-efficiency random fiber laser, featuring a linear output as well. The lasing cavity incorporates a section of standard single-mode fiber and a band-selective point reflector placed at the far end of the fiber. The numerical result indicates that most energy is further pushed toward the pump side comparing with the open cavity scheme, producing a high-efficiency output. Then, we analyze the dependence of threshold and slope efficiency on cavity length and pumping wavelength. Most importantly, shorter cavity length would yield higher efficiency, and for different pumping wavelengths, there will be different cavity lengths corresponding to the lowest lasing threshold. Finally, we deliberately choose the parameters and experimentally achieve an 1145-nm random fiber laser with 7.13-W output and >90% slope efficiency (with 10-W pump), while the slope efficiency is almost constant above the 2-W lasing threshold. This letter provides a comprehensive guideline for designing such random fiber lasers with tailored performance.
