Suppression of self-pulsing in an erbium-doped fiber laser

Optics Letters, 1997
We propose a scheme whereby the self-pulsation that commonly occurs in an erbium-doped fiber laser can be suppressed. The scheme consists of the addition of a low-power laser as an auxiliary pump. The required auxiliary pump power is only a few percent of the output lasing power.

CVD-grown MoSe2 with high modulation depth for ultrafast mode-locked erbium-doped fiber laser

Nanotechnology, 2018
Two-dimensional materials have been widely used as optical modulator materials in mode-locked fiber lasers. In terms of the performance of the fiber laser, one with an ultrashort pulse and high stability has great commercial value.

Erbium-doped fiber lasers as deep-sea hydrophones

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2006
The present work deals with the development of a prototype of hydrophone for deep see acoustic detection. The base sensitive element is a single mode erbium-doped fiber laser. The high sensitivity make these sensors very suitable for a wide range of deep see acoustic applications, including the geological survey, the marine mammals survey and overall ...

Characteristics of the intracavity dispersion in an erbium-doped fiber laser

Optics Letters, 1999
We have found theoretically that the intracavity dispersion of a laser is independent of the pumping power and wavelength and that the resonant group-velocity dispersion vanishes. We have experimentally observed that the intracavity dispersion of an erbium-doped fiber laser was independent of the pumping power and wavelength within the measuring error,

Tunable and switchable C-band and L-band multi-wavelength erbium-doped fiber laser employing a large-core fiber filter

Optics and Laser Technology, 2019
In this paper, we propose and experimentally demonstrate a C- and L-band erbium-doped fiber laser (EDFL) with tunable single-, dual- and triple-wavelength lasing emissions. A tapered structure large-core fiber filter (LCFF) is inserted to serve as tuning

Passively Q-switched and mode-locked Erbium-doped fiber laser with topological insulator Bismuth Selenide (Bi2Se3) as saturable absorber at C-band region

Optical fiber technology (Print), 2019
We experimentally demonstrate Q-switched and mode-locked Erbium-doped fiber laser (EDFL) by using topological insulator (TI) Bismuth Selenide (Bi2Se3) as saturable absorber (SA). The fabricated Bi2Se3 SA exhibits modulation depth and saturation intensity
