Furthermore, the output wavelength of the Brillouin random laser can be tunable in the range of from 1529 nm to 1588 nm with the Stokes order number remained 7, indicating that the random fiber laser has a wavelength adjustable range of 36 nm....
Such a graphene-based architecture not only provides a tunable pulsed random laser for fiber-optic sensing, speckle-free imaging, and laser-material processing, but also a new way for the non-random CW fiber lasers to generate widely tunable and singly-polarized pulses....

In this paper, a few-mode fiber filter-based cascaded high-order tunable multi-wavelength random Raman fiber laser (MWRRFL) is demonstrated, for the first time, in which a tuning range covers the 1.1–1.5μm band. In the half-open MWRRFL, a few-mode fiber-based intermodal interferometer ...
A tunable random distributed feedback (RDFB) fiber laser operating at 1 μm is presented, which consists of a piece of ytterbium-doped fiber, a manual tunable filter and a 1-km-long single-mode fiber that provides RDFB. The wavelength of the RDFB fiber laser can be...

In this work, we demonstrate a broadband tunable single-longitudinal-mode (SLM) random laser based on Rayleigh backscattering in a standard single-mode fiber. The wide tuning range of this SLM fiber laser over 1500–1570 nm is demonstrated with a linewidth of 4.5–30 kHz. The tuning is achie...
