860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)
Results in Physics, 2019 We proposed and demonstrated a high power mode-locked fiber laser using a new type of gain medium which is called as Erbium Gallium co-doped fiber (Ga-EDF). The mode-locking mechanism is enabled by a graphene-based saturable absorber, which is fabricated

Stability calculations for the ytterbium-doped fiber laser passively mode-locked through nonlinear polarization rotation [PDF]
, 2004 We investigate theoretically a fiber laser passively mode-locked with nonlinear polarization rotation. A unidirectional ring cavity is considered with a polarizer placed between two sets of a halfwave plate and a quarterwave plate.

Models for Passively Mode-Locked Fiber Lasers [PDF]
2008 10th Anniversary International Conference on Transparent Optical Networks, 2008 We give a review of theoretical approaches we have recently developed for the description of passively mode-locked fiber lasers. Mode-locking is assumed to be obtained with nonlinear polarization rotation. The first approach takes the form of a cubic Ginzburg-Landau equation where the coefficients take into account the orientation of the phase plates ...

Actively mode-locked Raman fiber laser
Optics Express, 2015 Active mode-locking of Raman fiber laser is experimentally investigated for the first time. An all fiber connected and polarization maintaining loop cavity of ~500 m long is pumped by a linearly polarized 1120 nm Yb fiber laser and modulated by an acousto-optic modulator.

, 2013 Nowadays, to satisfy the increase of internet demands and requirement, two multiplexing techniques are used: WDM (Wavelength Division Multiplex) and TDM (Time Division Mul‐ tiplex). WDM still more used than TDM. However, for practical system applications, such as optical CDMA (Code Division Multiplex Access) and OTDM (Optical Time Division Multi‐ plex)
