Stable Triple-Wavelength Random Fiber Laser Based on Fiber Bragg Gratings
Photonics, 2023 We demonstrate a generation of three lasing wavelengths with the assistance of Rayleigh backscattering as the stabilizer of peak power variations. The proposed laser consists of a combination of the semiconductor optical amplifier (SOA) and erbium-doped ...

Hybrid electronically addressable random fiber laser
Optics Express, 2020 We report here a novel architecture for a random fiber laser exploiting the combination of a semiconductor optical amplifier (SOA) and an erbium doped fiber (EDF). The EDF was optically biased by a continuous wave pump laser, whereas the SOA was arranged in a fiber loop-mirror and driven by nanosecond duration current pulses. Laser pulses were obtained

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.

Random raman fiber laser based on a twin-core fiber with FBGs inscribed by femtosecond radiation [PDF]
, 2019 Narrowband Raman lasing in a polarization-maintaining two-core fiber (TCF) is demonstrated. Femtosecond point-by-point inscription of fiber Bragg gratings (FBGs) in individual cores produces a half-open cavity with random distributed feedback.

Experimental demonstration of 25 GHz wideband chaos in symmetric dual port EDFRL [PDF]
, 2017 We study dynamics of chaos in dual port erbium-doped fiber ring laser (EDFRL). The laser consists of two erbium-doped fibers, intracavity filters at 1549.30 nm, isolators, and couplers.
