Physical Review A, 2011
An optical fiber is treated as a natural one-dimensional random system where lasing is possible due to a combination of Rayleigh scattering by refractive index inhomogeneities and distributed amplification through the Raman effect. We present such a random fiber laser that is tunable over a broad wavelength range with uniquely flat output power and ...

Quasi-kilowatt random fiber laser
Optics Letters, 2019The random distributed-feedback Raman fiber laser (RRFL) is a new approach to obtain a high-power laser. In this Letter, we report a RRFL with quasi-kilowatt output power for the first time based on a half-open cavity. It consists of a piece of a large-mode-area passive fiber with a core diameter of 20 μm and a high-reflectivity fiber Bragg grating ...

Random Raman Supercontinuum fiber laser
Optica Advanced Photonics Congress 2022, 2022We demonstrate the generation of a supercontinuum from modulation instability and Raman self-frequency shift in a distributed feedback random Raman fiber laser. This laser has the potential for random number generation at Tbps speeds.

Random fiber laser based on artificially controlled backscattering fibers
Applied Optics, 2017The random fiber laser (RFL), which is a milestone in laser physics and nonlinear optics, has attracted considerable attention recently. Most previously reported RFLs are based on distributed feedback of Rayleigh scattering amplified through the stimulated Raman-Brillouin scattering effect in single-mode fibers, which require long-distance (tens of ...

Power scalability in random Raman fiber laser based on a random fiber grating
Conference on Lasers and Electro-Optics, 2021We report a novel high-power single-wavelength random Raman fiber laser based on the localized random feedback provided by an ultrashort random fiber grating inscribed by a femtosecond laser.

Random fiber laser directly pumped by a high-power laser diode
Optics Letters, 2013A random lasing based on Rayleigh scattering (RS) in a passive fiber directly pumped by a high-power laser diode (LD) has been demonstrated. Owing to the RS-based random distributed feedback (RDFB) the low-quality LD beam (938 nm) is converted into the high-quality laser output (980 nm). Because of the relatively low excess above the threshold with the

Random fiber laser based on a partial-reflection random fiber grating for high temperature sensing
Optics Letters, 2021A stable single wavelength random fiber laser (RFL) with a partial-reflection random fiber grating (PR-RFG) for high temperature sensing is proposed and demonstrated for the first time, to the best of our knowledge. The PR-RFG is fabricated with the help of a femtosecond laser, with its highest reflection peak significantly higher than all other ...

The rising power of random fiber laser
2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017We report on the demonstration of a 418 W high power random fiber laser, which is the highest power to the best of our knowledge. The random laser is a half-open cavity based on 130 meters long passive fiber with core diameter of 20 μm. It is pumped by 1070 nm Yb-doped fiber laser. The central wavelength of 1st order random laser is 1120 nm. The output
