Passively Q-Switched Er-Doped Fiber Lasers Using Alcohol
TL;DR: In this paper, a passively Q-switched Er-doped fiber laser using a simple and cost-effective saturable absorber (SA) of alcohol has been demonstrated, which is made through filling anhydrous alcohol in the gap between the endfacets of two optical patch cords, which are inserted into a cannula.

Large-region tunable optical bistability in saturable absorber-based single-frequency Brillouin fiber lasers
TL;DR: In this paper, the optical bistability in a single-frequency Brillouin fiber laser has been investigated, where a Sagnac fiber loop with unpumped erbium-doped fiber is embedded in the BFL cavity as a saturable absorber.
Tunable bistability in hybrid Brillouin–erbium single-frequency fiber laser with saturable absorber
TL;DR: In this paper, a single-frequency hybrid Brillouin-erbium fiber laser with a saturable absorber is used to suppress the multiple-longitudinal mode operation. But the results show that the proposed fiber laser performs a single longitudinal mode status with excellent stability of the output wavelength and optical power.

Superluminal propagation through 500 m optical fiber via stimulated Brillouin scattering.
TL;DR: Brillouin-induced loss resonance for fast light generation of pump signals is achieved in a single frequency Brillouin lasing oscillator with a highly nonlinear fiber as the SBS medium, which is the longest superluminal propagating distance reported so far.

Enhanced negative group velocity propagation in a highly nonlinear fiber cavity via lased stimulated Brillouin scattering
TL;DR: In this paper, a 10-m highly nonlinear fiber (HNLF) ring cavity was used for negative group velocity superluminal propagation with high Brillouin gain coefficient and the optimized 1∕99 coupler ratio.
