Temporal ghost imaging with random fiber lasers
Optics Express, 2020 Ghost imaging in the time domain has opened up new possibilities to retrieve ultrafast waveforms. A pre-requisite to ghost imaging in the time domain is a light source with random temporal intensity fluctuations that are fully uncorrelated over the duration of the temporal waveform being imaged.

Transient replica symmetry breaking in Brillouin random fiber lasers
PhotoniX, 2023 Replica symmetry breaking (RSB), as a featured phase transition between paramagnetic and spin glass state in magnetic systems, has been predicted and validated among random laser-based complex systems, which involves numerous random modes interplayed via

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.

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 ...

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.

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.
