C-band switchable multi-wavelength erbium-doped fiber laser based on Mach–Zehnder interferometer employing seven-core fiber

Optical Fiber Technology, 2018
In this study, we propose and test a linear cavity erbium-doped fiber laser that incorporates a seven-core-based Mach–Zehnder interferometer (MZI). A 3.6-m-long erbium-doped fiber was selected as the gain medium. The all-fiber MZI was composed of two 105/

FIrpic thin film as saturable absorber for passively Q-switched and mode-locked erbium-doped fiber laser

Optical fiber technology (Print), 2019
In this paper, we demonstrate the generation of passive all-fiber Q-switched and mode locked erbium doped fiber lasers (EDFLs) by using Bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato) iridium(III) (FIrpic) as a saturable absorber (SA).

Characteristics of an erbium-doped fiber laser

Optical Engineering, 1993
A study of the erbium-doped multicomponent glass fiber laser pumped by an argon ion laser is presented. Simultaneous laser oscillation in (a) the 1535- and 1550-nm bands and (b) 1550- and 1565-nm bands were observed, and the results indicate the possibility of achieving laser oscillations simultaneously at all three wavelength bands-of interest in ...

Effects of concentration and clusters in erbium-doped fiber lasers

Optics Letters, 1993
We report a low-threshold, high-conversion-efficiency erbium-doped fiber laser in a 100-parts-in-106 fiber pumped at 1.48 μm. The threshold and efficiency are found to deteriorate noticeably as the erbium concentration is increased. We propose that this is due mostly to rapid cross relaxation between ion pairs or clusters, and through modeling we show ...

Gourd-shaped subring resonator-based single longitudinal mode erbium-doped fiber laser

Optical Engineering: The Journal of SPIE, 2019
. A gourd-shaped subring resonator (GSR)-based single longitudinal mode erbium-doped fiber laser (EDFL) is proposed and experimentally demonstrated. The GSR can effectively expand the free spectral range of the fiber laser due to the Vernier effect and ...

Acoustically tuned erbium-doped fiber ring laser

Optics Letters, 1991
We report what is to our knowledge the first narrow-linewidth, continuously tunable laser that uses an acousto-optic filter to achieve a broad tuning range. The unidirectional ring-laser configuration incorporates an erbium-doped fiber amplifier as the gain medium and an integrated, frequency-shift-compensated acousto-optic filter as the tuning element.

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).

Passive modelocking of an erbium-doped fiber laser

Optical Amplifiers and Their Applications, 1990
Passive modelocking of an all-fiber erbium laser using a nonlinear optical loop mirror has been demonstrated. A terahertz modelocked bandwidth was observed.

Ultrashort pulse generation with an erbium-doped fiber laser ring cavity based on a copper oxide saturable absorber.

Applied Optics, 2018
A soliton mode-locked erbium-doped fiber (EDF) laser has been experimentally demonstrated using copper oxide (CuO) thin film as a saturable absorber (SA).

Self-pulsing in Erbium-doped fiber laser

2015 Optoelectronics Global Conference (OGC), 2015
We report the study of self-pulsing behavior in erbium-doped fiber laser due to the ion-pair formation and scattered feedback. We observed the high doping concentration of the laser to be the main cause of the pulsing phenomenon. We also demonstrate that the self pulsing can be suppressed by resonance pumping.
