Graphene mode locked, wavelength-tunable, dissipative soliton fiber laser
, 2010 Atomic layer graphene possesses wavelength-insensitive ultrafast saturable absorption, which can be exploited as a full-band mode locker. Taking advantage of the wide band saturable absorption of the graphene, we demonstrate experimentally that wide ...

Soliton crystal fiber laser [PDF]
, 2008 We report on the observation of bound state of some hundreds of solitons in a passively mode-locked Er:Yb-doped fiber laser. A double-clad fiber is used in a unidirectional ring cavity where the mode-locking is obtained thanks to the nonlinear ...

High-Energy Passive Mode-Locking of Fiber Lasers [PDF]
International Journal of Optics, 2012 Mode-locking refers to the generation of ultrashort optical pulses in laser systems. A comprehensive study of achieving high-energy pulses in a ring cavity fiber laser that is passively mode-locked by a series of waveplates and a polarizer is presented in this paper.

Advanced Healthcare Materials, EarlyView.ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.

Graphene mode locked fiber laser [PDF]
, 2019 Fiber laser is a perfect platform to generate and study the scalar and vector optical solitons. The optical solitons formation in fiber lasers is a result of the mutual interaction among the cavity dispersion, fiber nonlinearity, laser gain saturation and gain bandwidth filtering.
