“…When 8.97 W pump light centered at 1036.5 nm is launched into the half-open cavity, we obtain the maximum output power of 2.15 W from Output A. At the same time, by doing integration based on the spectrum data and measuring the total power from Output B, residual 1036.5 nm pump power is down to 22 mW, and the power of spontaneous Raman scattering from Output B is 3.26 W. The power leakage is relatively high due to the narrow linewidth of the FBG, and the other reason is that the higher the generation power is, the more pronounced the nonlinear spectral broadening is [24]. Also, it cannot achieve narrow linewidth emission from Output B.…”

Abstract:In this paper, we demonstrate a narrow linewidth random fiber laser, which employs a tunable pump laser to select the operating wavelength for efficiency optimization, a narrow-band fiber Bragg grating (FBG) and a section of single mode fiber to construct a half-open cavity, and a circulator to separate pump light input and random lasing output. Spectral linewidth down to 42.31 GHz is achieved through filtering by the FBG. When 8.97 W pump light centered at the optimized wavelength 1036.5 nm is launched into the half-open cavity, 1081.4 nm random lasing with the maximum output power of 2.15 W is achieved, which is more powerful than the previous reported results.

Random lasing (RL) characteristics of second-order random fiber laser formed solo by dispersion compensated fiber are studied. It is found that the threshold of first-order RL is only 0.45 W. In addition, a special route to stable second-order lasing is revealed, i.e., a special arc-shape output spectrum of secondorder RL and three chaotic regimes during evolution from the first RL to the second-order one with increased pump power.

“…It was shown theoretically [19,57,66] and experimentally [31] that Raman fibre lasers including random fibre lasers can exhibit such rare, short lived, high intensity events, facilitated by the underlying turbulent four wave mixing dynamics. The polarized nature of rogue events have been reported in numerical solutions of the Manakov system of Schrödinger equations [67], and in the vector Ginzburg Landau model simulations of the Raman fibre laser [68].…”

Fibre lasers are light sources that are synonymous with stability. They can give rise to highly coherent continuous-wave radiation, or a stable train of mode locked pulses with well-defined characteristics. However, they can also exhibit an exceedingly diverse range of nonlinear operational regimes spanning a multi-dimensional parameter space. The complex nature of the dynamics poses significant challenges in the theoretical and experimental studies of such systems. Here, we demonstrate how the real-time experimental methodology of spatio-temporal dynamics can be used to unambiguously identify and discern between such highly complex lasing regimes. This two-dimensional representation of laser intensity allows the identification and tracking of individual features embedded in the radiation as they make round-trip circulations inside the cavity. The salient features of this methodology are highlighted by its application to the case of Raman fibre lasers and a partially mode locked ring fibre laser operating in the normal dispersion regime.
