Measurement of the optical dielectric properties of thin-film materials by ultrafast time-resolved interferometry

open access: yesResults in Physics, 2020
We report a time-resolved optic interferometry (TROI) that enables to straightway probe the optical properties of traditional and special thin-film materials by feat of a phase delayed-interference between double beams of femtosecond laser synchronously ...

Investigation of photodamage by femtosecond laser to cells via gold nanorods [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2017
Usually, only focused femtosecond (fs) lasers at near-infrared (NIR) range can induce photodamage to transparent cells, making it difficult to treat large amount of cells by such optical methods for photostimulation.

Transition from ultrafast laser photo-electron emission to space charge limited current in a 1D gap

open access: yes, 2014
A one-dimensional (1D) model has been constructed to study the transition of the time-dependent ultrafast laser photo-electron emission from a flat metallic surface to the space charge limited (SCL) current, including the effect of non-equilibrium laser ...

Exciton‐Polaritons in Nanoscale Metal‐Organic Frameworks: A Platform for the Reversible Modulation of Strong Light‐Matter Coupling via the Chemical Environment

open access: yesAdvanced Functional Materials, EarlyView.
Strong exciton‐photon coupling is achieved by integrating porphyrin ligand‐based MOF nanoparticles in optical cavities, as evidenced by pronounced polariton branch anticrossing. The porous nature of the resonator enables precise, reversible tuning via vapor pressure, unlocking unprecedented chemical‐environment controlled dynamic polaritonic platforms ...

Incoherent x-ray scattering in single molecule imaging

open access: yesNew Journal of Physics, 2014
Imaging of the structure of single proteins or other biomolecules with atomic resolution would be enormously beneficial to structural biology. X-ray free-electron lasers generate highly intense and ultrashort x-ray pulses, providing a route towards ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Ultrafast Laser Filamentation in Transparent Solids

open access: yesUltrafast Science, 2023
Ultrafast laser filamentation results from the interaction of ultrafast laser with Kerr media. During filamentary propagation, the transparent medium is altered by numerous linear and nonlinear effects of ultrashort laser pulses.

Dispersion Measurement of Ultra-High Numerical Aperture Fibers covering Thulium, Holmium, and Erbium Emission Wavelengths

open access: yes, 2018
We present broadband group velocity dispersion (GVD) measurements of commercially available ultra-high numerical aperture fibers (UHNA1, UHNA3, UHNA4, UHNA7 and PM2000D from Coherent-Nufern). Although these fibers are attractive for dispersion management
