Tunable Single-Longitudinal-Mode High-Power Fiber Laser

International Journal of Optics, 2012
We report a novel CW tunable high-power single-longitudinal-mode fiber laser with a linewidth of ∼9 MHz. A tunable fiber Bragg grating provided wavelength selection over a 10 nm range. An all-fiber Fabry-Perot filter was used to increase the longitudinal

Strong Linewidth Reduction by Compact Brillouin/Erbium Fiber Laser

IEEE Photonics Journal, 2014
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.

Wavelength-tunable passively mode-locked Erbium-doped fiber laser based on carbon nanotube and a 45° tilted fiber grating

, 2018
A wavelength-tunable all-fiber Erbium-doped mode-locked fiber laser based on carbon nanotubes and 45° tilted fiber grating (TFG) is demonstrated. We investigated the effect of PDL of 45TFG in the tuning range of a mode locked laser.
