Thermically tuned erbium-doped fiber ring laser

2003 Conference on Lasers and Electro-Optics Europe (CLEO/Europe 2003) (IEEE Cat. No.03TH8666), 2005
In this work we demonstrate the use of an all-fiber technique to get a continuously tunable ring-laser of narrow linewidth, by using of all-fiber Sagnac interferometer like a thermically selective optical filter (TSOF), in gain region of Er-doped fiber, as the continuously tunable wavelength-selective element in a fiber ring laser.

Saturable Absorption in Erbium-doped Fiber and Optical Bistability in Erbium-doped Fiber Ring Laser

2021 Photonics North (PN), 2021
Saturable absorption in erbium-doped fiber is presented through absorption measurements using a tunable laser and variable power. Its consequent optical bistability is also observed in erbium-doped fiber ring laser with long lengths of the fiber. Higher absorption at shorter wavelengths enables a wider bistable range.

A fiber-coupled erbium-doped microsphere laser

Conference on Lasers and Electro-Optics (CLEO 2000). Technical Digest. Postconference Edition. TOPS Vol.39 (IEEE Cat. No.00CH37088), 2000
Summary form only given. Optical microsphere cavities, with their very high quality-factor and sub-millimeter dimensions, are attractive new building block for fiber optics and photonics. A microsphere made of laser-active material, with an efficient optical pumping scheme, can be configured as a miniature solid-state laser. Because of the small volume

New erbium doped fiber laser amplifier

2011 Saudi International Electronics, Communications and Photonics Conference (SIECPC), 2011
A new configuration of laser and amplifier is constructed and investigated. This configuration is called erbium doped fiber laser amplifier (EDFLA) where both the laser and amplifier are included in one configuration. The new configuration is utilized as optical amplifier, laser source, and ON/OFF optical tool.

Modeling of erbium doped fiber ring laser

Optics Communications, 1997
Abstract A numerical model for the analysis of the continuous wave operation of an erbium doped fiber ring laser is presented. The model has been obtained by developing the so called spectral one already presented for the analysis of erbium doped fiber amplifiers (EDFA).

Erbium-doped photonic crystal fiber chaotic laser

SPIE Proceedings, 2011
An erbium-doped photonic crystal fiber laser has been designed, constructed and characterized in order to examine the feasibility of this kind of devices for secure communications applications based on two identical chaotic lasers. Inclusion of a tailored photonic crystal fiber as active medium improves considerably the security of the device because

Characterization of Erbium Doped Fiber Ring Laser

2020 28th Signal Processing and Communications Applications Conference (SIU), 2020
In this study, the output power and wavelength tuning performance of ring type erbium doped fiber laser (EDFL) were examined theoretically and experimentally. In order to investigate the effects of parameters such as erbium doped fiber (EDF) length, output coupler ratio, erbium ion density, pump power on the performance of ring-type EDFL, two-level ...

Vector self-pulsing in erbium-doped fiber lasers

Optics Letters, 2016
Insight into instabilities of fiber laser regimes leading to complex self-pulsing operations is an opportunity to unlock the high power and dynamic operation tunability of lasers. Though many models have been suggested, there is no complete covering of self-pulsing complexity observed experimentally.

Electronically tuned erbium-doped fiber ring lasers

Integrated Photonics Research, 1991
We have made electronically-tuned erbium-doped fiber ring lasers using two very different means of wavelength selection: a liquid-crystal-filled Fabry-Perot etalon filter1 and a frequency-shift-free two-stage integrated acousto-optic filter.2 Both lasers exhibited a broad tuning range (50 nm), continuous tunability, linewidths of only a few kHz, 70 ...
