Q-switching and mode-locking pulse generation with graphene oxide paper-based saturable absorber
The Journal of Engineering, 2015 Q-switched and mode-locked erbium-doped fibre lasers (EDFLs) are demonstrated by using non-conductive graphene oxide (GO) paper as a saturable absorber (SA).

Finite-difference time-domain methods to analyze ytterbium-doped Q-switched fiber lasers
, 2016 Q-switched lasers are widely used in material processing, laser ranging, medicine, and nonlinear optics-in particular, Q-switched lasers in optical fibers are important since they cannot only generate high peak powers but can also concentrate high peak ...

Advanced Materials, EarlyView.The interfacial spin‐orbit interaction in single‐crystalline Fe1−xCox thin films grown on GaAs(001) can be continuously tuned via alloying. Using spin‐orbit ferromagnetic resonance, the authors find that the interfacial spin‐orbit fields exhibit a nonmonotonic dependence on Co concentration, with a minimum at 20% Co. ABSTRACT The discovery of intrinsic

A review of laser and light therapy in melasma
International Journal of Women's Dermatology, 2017 Melasma is a dysregulation of the homeostatic mechanisms that control skin pigmentation and excess pigment is produced. Traditional treatment approaches with topical medications and chemical peels are commonly used but due to the refractory and recurrent

Epitaxially Integrated Electro‐Optic KNbO3 Thin Films on Silicon
Advanced Materials, EarlyView.We demonstrate the first epitaxial integration of electro‐optic KNbO3 thin films on silicon using suboxide molecular‐beam epitaxy. Combining adsorption‐controlled molecular‐beam epitaxy, advanced characterization, and phase‐field modeling, we demonstrate phase‐pure crystalline films mirroring bulk crystals with robust Pockels response, enabling future ...

Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors
Advanced Materials, EarlyView.Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

A diode-pumped passively Q-switched Tm,Ho:YAP laser with a single-walled carbon nanotube
, 2013 In this letter we present diode-pumped continuous wave (CW) and passively Q-switched a-cut and b-cut Tm,Ho: YAP lasers with a single-walled carbon nanotube saturable absorber (SWCNT-SA).

Demagnetization‐Driven Nanoscale Chirality‐Selective Phonon Transport
Advanced Materials, EarlyView.Chiral heat flow is switched in a ferromagnet/chiral α‐SiO2 heterostructure by controlling the angular momentum of demagnetization‐driven chiral phonons. When phonon handedness matches the crystal chirality, nanoscale thermal transport is enhanced; the opposite handedness suppresses transport, establishing a magnetization‐tunable chiral phonon diode ...
