Tunable Random Fiber Laser Based on Dual-Grating Structure [PDF]
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 ...

Review of Random Fiber Lasers for Optical Fiber Sensors [PDF]
Sensors, 2023 A random fiber laser does not need a traditional resonant cavity and only uses the multiple scattering of disordered media to provide feedback to achieve laser output.

Triple-Wavelength Thulium-Doped Fiber Random Laser Based on Random Fiber Grating [PDF]
Photonics, 2023 We demonstrate a triple-wavelength thulium-doped fiber random laser using a 10 cm long random fiber grating to provide random distributed feedback and a superimposed fiber Bragg grating as the wavelength-selective mirror.

Advances in Random Fiber Lasers and Their Sensing Application [PDF]
Sensors, 2020 Compared with conventional laser, random laser (RL) has no resonant cavity, reducing the requirement of cavity design. In recent years, the random fiber laser (RFL), a novel kind of RL, has made great progress in theories and experiments.

Internal modulation of a random fiber laser [PDF]
Optics Letters, 2013 A characterization of a modulated random mirror laser has been experimentally carried out. Unlike conventional internally modulated fiber lasers, no distortion of the modulating frequency or self-mode-locking effects were measured. The behavior of the laser using pulsed and analog modulation up to 12 GHz is shown.

LD-Pumped Random Fiber Laser Based on Erbium-Ytterbium Co-Doped Fiber
Photonic Sensors, 2019 In this paper, a cladding-pumped erbium-ytterbium co-doped random fiber laser (EYRFL) operating at 1550 nm with high power laser diode (LD) is proposed and experimentally demonstrated for the first time.

Turbulent Intermittency in a Random Fiber Laser [PDF]
Atoms, 2019 In fluid turbulence, intermittency is the emergence of non-Gaussian tails in the distribution of velocity increments in small space and/or time scales. Intermittence is thus expected to gradually disappear as one moves from small to large scales. Here we

Perovskite random lasers on fiber facet
Nanophotonics, 2020 Hybrid lead halide perovskites have made great strides in next-generation photovoltaic and optoelectronic devices. Random lasers based on perovskite materials have been intensively investigated, but the miniaturization of perovskite random lasers has not
