L-Band Erbium Fiber Laser with Tunable and Narrow Sub-kHz Linewidth Output
In this paper, a wavelength-selectable erbium-doped fiber (EDF) laser in L-band bandwidth with a simple structure and low cost is described. To obtain stable single-longitudinal-mode (SLM) and narrow laser linewidth, the 2 m unpumped EDF-based saturable ...

Strong Linewidth Reduction by Compact Brillouin/Erbium Fiber Laser
We demonstrate the strong linewidth reduction by a compact Brillouin/erbium fiber laser (BEFL), in which 4-m erbium-doped fiber (EDF) acts as both the Brillouin and linear gain media.

Five Orders of Cascaded Raman Fibre Laser Oscillation From 1550 nm to Mid‐IR at 2334 nm Wavelength
We experimentally demonstrate five orders of cascaded Raman oscillations (Raman lasers) in a fibre, starting from ∼1550 nm until 2334 nm. ABSTRACT We demonstrate a cascaded Raman fibre laser (RFL) oscillation up to the fifth order Stokes wave, from ∼1550 nm to mid‐IR at 2334 nm, with silica fibres.
