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.

Carbon dots (CDs) have attracted much attention for applications in photonics and optoelectronics because of their high emission efficiency and ease of synthesis. Although studies in solution are well established, solid‐state applications are less common because of optical quenching phenomena that critically affect CDs. Herein, the synthesis of amorphous CDs from citric acid, operating as hosts of dye molecules, and their incorporation into organic–inorganic silica matrices through a fast photo‐induced polymerization process are reported. The photocurable sol composition allows easy dispersion of nanometer‐sized scattering centers, such as titania or gold nanoparticles (NPs), which have been incorporated, along with CDs, into nanocomposites. The combination of high‐brightness CDs and nanoscatterers in the hybrid matrices allows for achieving and investigating the random lasing processes occurring in the orange‐red range of the visible spectrum. In situ‐grown gold NPs contribute to a significant improvement in solid‐state lasing, enabling an emission as narrow as 5 nm and a laser threshold as low as 0.3 mJ pulse−1. The present approach reveals the technological and scientific potential of CDs when embedded in solid‐state disordered active media.

This study investigates the kinetics of rhodamine B diffusion over a multilayer membrane composed of silk fibroin hydrogel and polyethylene terephthalate (PET) nonwoven fabric. To evaluate the impact of varying membrane structure thicknesses on dye diffusion rate, we used 2, 4, 8, 16, and 32 layers. The research indicated that the 32-layer membrane significantly slowed dye penetration. An initial linear release was seen until 2500 minutes, after which the rate of diffusion decelerated. Validation of the controlled diffusion behavior across the hydrogel layers was achieved by UV-Vis spectroscopic analysis, specifically targeting the absorbance peak at 554 nm of rhodamine B. The results of this study provide crucial insights for the advancement of hydrogel- based materials in sensor technologies, drug delivery approaches, and regulated dye release.
