Random fiber laser based on artificially controlled backscattering fibers

Applied Optics, 2017
The 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 ...

Vortex random fiber laser with controllable orbital angular momentum mode

, 2021
In this paper, we propose and experimentally demonstrate a vortex random fiber laser (RFL) with a controllable orbital angular momentum (OAM) mode. The topological charge of the vortex RFL can range from −50 to 50 with nearly watt-level output power.

Nonlinear dynamics of four-wave mixing, cascaded stimulated Raman scattering and self Q-switching in a common-cavity ytterbium/Raman random fiber laser

, 2021
The combined effect of stimulated Raman scattering (SRS), four-wave mixing (FWM) and self-pulsation in optical fibers can be either beneficial or detrimental, depending upon a specific application.

The rising power of random fiber laser

2017 16th International Conference on Optical Communications and Networks (ICOCN), 2017
We 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
