Ultrafast X-ray diffraction probe of terahertz field-driven soft mode dynamics in SrTiO3

open access: yesStructural Dynamics, 2017
We use ultrafast X-ray pulses to characterize the lattice response of SrTiO3 when driven by strong terahertz fields. We observe transient changes in the diffraction intensity with a delayed onset with respect to the driving field ...

Influence of laser spot size at diffuser plane on the longitudinal spatial coherence function of optical coherence microscopy system

open access: yes, 2019
Coherence properties and wavelength of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal to noise ratio, axial resolution, and penetration depth of the system.

Designs of Time-Resolved Resonant Inelastic X-Ray Scattering Branchline at S3FEL

open access: yesPhotonics
With the rapid development of X-ray free-electron lasers (XFELs), time-resolved resonant inelastic X-ray scattering (tr-RIXS) has attracted more attention.

Squeezed-light source for the superresolving microscopy

open access: yes, 2004
We propose a source of multimode squeezed light that can be used for the superresolving microscopy beyond the standard quantum limit. This source is an optical parametric amplifier with a properly chosen diaphragm on its output and a Fourier lens.

Unravelling the electrochemical double layer by direct probing of the solid/liquid interface

open access: yesNature Communications, 2016
The electrochemical double layer is a key concept in chemistry, but its properties are hard to probe experimentally. Here, the authors use ambient pressure X-ray photoelectron spectroscopy to probe the electrochemical double layer potential profile at ...

Rapid-response, light-exposure control system [PDF]

open access: yes, 1968
Rapid-response electro-optical, light exposure control system, will maintain the light reaching a camera film or other light-sensitive detector at essentially constant level, despite wide variations in the brightness of the light source.

Enhanced electron emission from coated metal targets: Effect of surface thickness on performance

open access: yesAIP Advances, 2018
In this work, we establish an analytical formalism to address the temperature dependent electron emission from a metallic target with thin coating, operating at a finite temperature.
