“…Qi et al have shown that via forming a backward-pumped fully open common-structure ytterbium/Raman RFL (depicted in Figure 9b) to suppress the forward Raman scattering, the spectral purity can reach as high as 99.4% and 99.5% for the continuous-wave and the pulsed first-order Raman random fiber lasing, respectively. [164] Furthermore, recently, an amplified broadened distributed Bragg reflection diode laser was introduced to enhance the performances of the cascaded RRFL. [17] Benefiting from the low-noise pump, the spectral purity of the cascaded random lasing is higher than 99%, and the RIN of such a sixth-order RRFL is less than −100 dBc Hz −1 in the frequency span of 9 kHz to 10 GHz.…”

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.

Since the concept of distributed feedback fiber random laser was put forward, random Raman fiber laser (RRFL) has made great progress in high power operation. For RRFL with a full-open cavity, the simplest cavity structure, further power scaling was restricted by the rapid increase of high-order Stokes wave. In this paper, we demonstrate that the output power of the RRFL can be further improved by optimizing the fiber length. The relationship between the RRFL output power and fiber length is researched theoretically and experimentally. Results show that to optimize the RRFL with a full-open cavity in output power to the best, the fiber length should be as short as possible, under the premise of avoiding causing strong four-wave mixing (FWM) and ensuring the sufficient absorption of signal light.
