Graphene Mode-Locked Ultrafast Laser [PDF]

ACS Nano, 2010
Graphene is at the center of a significant research effort. Near-ballistic transport at room temperature and high mobility make it a potential material for nanoelectronics. Its electronic and mechanical properties are also ideal for micro and nanomechanical systems, thin-film transistors and transparent and conductive composites and electrodes. Here we

Switchable Generation of Multipulse Patterns of Noise-Like Pulse and Dissipative Soliton Resonance in a Fiber Laser

IEEE Photonics Journal, 2019
We report on the switchable generation of versatile patterns of multiple noise-like pulse (NLP) and dissipative soliton resonance (DSR) pulses in a dual-pump figure-eight mode-locked fiber laser.

MXene saturable absorber enabled hybrid mode-locking technology: a new routine of advancing femtosecond fiber lasers performance

Nanophotonics, 2020
MXene is a promising two-dimensional (2D) material that is widely used in electro-photonic devices due to its unique properties. In this contribution, V2CTx, a novel MXene, was employed as a saturable absorber (SA) for hybrid passively mode-locked fiber ...

Multi-stabilities and symmetry-broken one-colour and two-colour states in closely coupled single-mode lasers [PDF]

, 2014
We theoretically investigate the dynamics of two mutually coupled identical single-mode semi-conductor lasers. For small separation and large coupling between the lasers, symmetry-broken one-colour states are shown to be stable.

Numerical simulation for generation of stable single mode-locked pulses from QML laser with EO modulator and V3+:YAG

Results in Physics, 2018
The instability of mode-locked pulses underneath Q-switched envelop limits the applications of Q-switched and mode-locked (QML) lasers. In this paper we present a developed theoretical model for QML laser at 1.3 µm.
