Wide-field coherent anti-Stokes Raman scattering microscopy based on picosecond supercontinuum source

APL Photonics, 2018
We present a wide-field coherent anti-Stokes Raman scattering microscopy setup based on picosecond-laser-pumped supercontinuum and use it to demonstrate video-rate imaging with chemical specificity. The broadband excitation allows simultaneous imaging of

Relation between squeezing of vacuum fluctuations, quantum entanglement and sub-shot noise in Raman scattering

, 2012
A completely quantum description of Raman process is used to investigate the nonclassical properties of the modes in the stimulated, spontaneous and partially spontaneous Raman process.

Hyperspectral volumetric coherent anti-Stokes Raman scattering microscopy: quantitative volume determination and NaCl as non-resonant standard [PDF]

, 2016
In this work, we demonstrate quantitative volume determination of chemical components in three dimensions using hyperspectral coherent anti-Stokes Raman scattering microscopy, phase-corrected Kramers–Kronig retrieval of the coherent anti-Stokes Raman ...

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

Advanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

Time resolved observation of resonant and non-resonant contributions to the nonlinear susceptibility χ(3) [PDF]

, 1978
The resonant and nonresonant part of χ(3) are distinguished by their different time behavior. The medium is coherently excited by two picosecond light pulses of defined frequency difference and the state of the system is monitored by a third properly ...

Enhancing Synaptic Plasticity and Multistate Retention of Organic Neuromorphic Devices Using Anion‐Excessive Gel Electrolyte

Advanced Functional Materials, EarlyView.
Anion‐excessive gel‐based organic synaptic transistors (AEG‐OSTs) that can maintain electrical neutrality are developed to enhance synaptic plasticity and multistate retention. Key improvement is attributed to the maintenance of electrical neutrality in the electrolyte even after electrochemical doping, which reduces the Coulombic force acting on ...

Theory‐Guided Design of Non‐Precious Single‐Atom Catalyst for Electrocatalytic Chlorine Evolution

Advanced Functional Materials, EarlyView.
To overcome the reliance on noble metals for the chlorine evolution reaction (CER), we designed a non‐precious single‐atom catalyst (SAC), NiN3O–O. It achieves a low overpotential of 75 mV, 95.8% Cl2 selectivity, and outperforms commercial dimensionally stable anodes (DSAs).

Two types of cooperation between the photons in multiple scattering lasing and their possible application

Physics Open
The two types of cooperative effects between the converted photons in the multiple steps of Raman lasing are proposed. The first type involves the cooperative process between the photons of one of the steps of Raman conversion.
