Bound Soliton Fiber Laser Mode-Locking Without Saturable Absorption Effect

IEEE Photonics Journal, 2016
Stable bound soliton laser mode-locking is experimentally demonstrated in an environmentally stable hybrid mode-locked Er-doped fiber laser without incorporating (equivalent) nonlinear saturable absorption effects.

Early Spatial and Contextual Coding Deficits in Hippocampal CA1 Precede Performance Decline in an Alzheimer's Disease Model

Advanced Science, EarlyView.
Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Pulse-shaping assisted nonlinear optical signal generation in fibres

, 2013
This thesis investigates pulse-shaping assisted nonlinear optical signal generation in fibers. A linear pulse shaping stage is included in nonlinear fibre optic systems to achieve flexible and precise control over the characteristics of the output signal.

Retiming dynamics of harmonically mode-locked laser solitons in a self-driven optomechanical lattice

Light: Science & Applications
Harmonic mode-locking, realized actively or passively, is an effective technique for increasing the repetition rate of ultrafast lasers. It is critically important to understand how a harmonically mode-locked pulse train responds to external ...

An Injectable ROS‐Responsive Nanozyme Hydrogel Regulates the Uterine Microenvironment to Prevent Intrauterine Adhesions

Advanced Science, EarlyView.
The injectable CeTA@GPP hydrogel is administered via intrauterine injection, forming a protective barrier. In the high ROS inflammatory microenvironment of injured endometrium, boronate ester cleavage triggers responsive CeTA release and local enrichment.

All-fiber laser mode-locked by the acousto-optic modulation of a fiber Bragg grating in suspended core fiber [PDF]

, 2015
An ytterbium-doped fiber laser mode-locked by the interaction of a fiber Bragg grating and longitudinal acoustic waves in a suspended core fiber is experimentally investigated. An optimized design of an acousto-optic modulator is also proposed.

Yb:tungstate waveguide lasers [PDF]

, 2011
Lasers find a wide range of applications in many areas including photo-biology, photo-chemistry, materials processing, imaging and telecommunications. However, the practical use of such sources is often limited by the bulky nature of existing systems.
