Extremely High-Quality Periodic Structures on ITO Film Efficiently Fabricated by Femtosecond Pulse Train Output from a Frequency-Doubled Fabry–Perot Cavity

Nanomaterials, 2023
This study developed a novel frequency-doubled Fabry–Perot cavity method based on a femtosecond laser of 1030 nm, 190 fs, 1 mJ, and 1 kHz. The time interval (60–1000 ps) and attenuation ratio (0.5–0.9) between adjacent sub-pulses of the 515 nm pulse ...

Theoretical Study on the Ultrafast Selective Excitation of Surface-Enhanced Coherent Anti-Stokes Raman Scattering Based on Fano Resonance of Disk-Ring Nanostructures by Shaped Femtosecond Laser Pulses

Photonics, 2022
The enhancement and selective excitation of coherent anti-Stokes Raman scattering (CARS) and the suppression of background noise are very important problems for real-time detection at the single-molecule level.

Broadband Second Harmonic Generation in a z-Cut Lithium Niobate on Insulator Waveguide Based on Type-I Modal Phase Matching

Photonics, 2023
We numerically investigate a second harmonic generation (SHG) in a z-cut lithium niobate on insulator (LNOI) waveguide based on type-I mode phase matching (MPM) between two fundamental modes.

Electron-beam spectroscopy for nanophotonics [PDF]

Nature Materials, 2019
Progress in electron-beam spectroscopies has recently enabled the study of optical excitations with combined space, energy and time resolution in the nanometer, millielectronvolt and femtosecond domain, thus providing unique access into nanophotonic structures and their detailed optical responses.

Uncertainty Relation and Quantum Phase Transition in the Two-Dimensional Ising Model

Frontiers in Physics, 2022
By using quantum renormalization group (QRG) approach, we first derive the effective Hamiltonian and QRG equations of the two-dimensional (2D) Ising models with two different time-dependent transverse magnetic fields analytically.

Synthesis, Structure and Photochemistry of Dibenzylidenecyclobutanones

Molecules, 2022
A series of symmetrical dibenzylidene derivatives of cyclobutanone were synthesized with the goal of studying the physicochemical properties of cross-conjugated dienones (ketocyanine dyes). The structures of the products were established and studied by X-

Electron Energy-Loss Spectroscopy [PDF]

Microscopy and Microanalysis, 1997
Solid-state scientists have many analytical techniques to choose from. But electron energy-loss spectroscopy does some things that no other technique can quite match. Electron energy-loss spectroscopy can, for example, form chemical maps of nanometre-sized regions in solid samples. It can be used to characterize interfaces buried deep in samples and to
