Tunable Random Fiber Laser Based on Dual-Grating Structure
Photonics, 2023 In order to reduce the pumping threshold and achieve a short-cavity single-mode transmission with a narrow-linewidth random fiber laser, we propose a tunable random fiber laser based on the combination of random grating and highly reflective fiber Bragg ...

Physical Review Letters, 2007 We investigate the effects of two dimensional confinement on the lasing properties of a classical random laser system operating in the incoherent feedback (diffusive) regime. A suspension of 250nm rutile (TiO2) particles in a Rhodamine 6G solution was inserted into the hollow core of a photonic crystal fiber (PCF) generating the first random fiber ...

Tunable random polymer fiber laser
Optics Express, 2017 We have demonstrated the realization of on-line temperature-controlled random lasers (RLs) in the polyhedral oligomeric silsesquioxanes (POSS) nanoparticles (NPs) as well as Pyrromethene 597 (PM597) laser dye, Fe3O4/SiO2 NPs as well as PM597, and only PM597 doped polymer optical fibers (POFs), respectively.

Plasmonic random laser on the fiber facet
Optics Express, 2015 A random laser on the optical fiber facet is constructed by dipping an optical fiber end face into the solution of polydimethylsiloxane doped with rhodamine 6G organic dye and silver nanowires. The PDMS film doped with rhodamine 6G acts as the active waveguide layer, and the silver nanowires provide a three-dimensional plasmonic feedback.

Random fiber lasers: Application to fiber optic sensors networks [PDF]
2017 19th International Conference on Transparent Optical Networks (ICTON), 2017 Recently, random mirrors have been proposed as a method to create fiber laser cavities. This kind of cavity is based on cooperative Rayleigh scattering, which is generated along a fiber due to the material inhomogeneities presented in that fiber.

Multi-parameter sensor based on random fiber lasers
AIP Advances, 2016 We demonstrate a concept of utilizing random fiber lasers to achieve multi-parameter sensing. The proposed random fiber ring laser consists of an erbium-doped fiber as the gain medium and a random fiber grating as the feedback.
