Attosecond‐Stable Two‐Dimensional Spectroscopy by a Sagnac‐Based Modulating System and a Sub‐4‐fs Continuum Source

Laser &Photonics Reviews, EarlyView.
A novel optical platform integrates a Sagnac‐based interferometer with a high‐brightness multiple‐plate continuum source to advance two‐dimensional electronic spectroscopy. The robust system delivers octave‐spanning, 3.7‐femtosecond pulses and achieves intrinsic attosecond‐level phase stability without active feedback.

Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching

Laser &Photonics Reviews, EarlyView.
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

Nonlocal Leaky Mode Metasurfaces for Mode‐, Angle‐, and Polarization‐Multiplexed Holography With Thermal Light

Laser &Photonics Reviews, EarlyView.
Nonlocal leaky mode metasurfaces reconstruct multiplexed holograms directly from unfiltered thermal light. High‐Q leaky guided modes compress broadband halogen emission into narrowband channels, enhancing temporal coherence a hundredfold, while a single nanohole array encodes independent images addressed by mode, angle, and polarization, establishing ...

Single‐Lens Counter‐Focused Ultrashort Laser Pulses for Enhanced Microplasma Formation Inside Silicon

Laser &Photonics Reviews, EarlyView.
A polarization‐dependent liquid–crystal spatial light modulator is used to generate coaxial double‐focus laser beams with independently tunable focal separation and intensity. Applied to silicon, this configuration enables counterpropagating pulse interactions using a single focusing element, enhancing nonlinear excitation and achieving near‐critical ...

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting

Macromolecular Rapid Communications, EarlyView.
Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Mechano‐Optical Behavior of Uniaxially Oriented Fluoropolymer Films: Ethylene Tetrafluoroethylene Copolymer (ETFE) and Tetrafluoroethylene Hexafluoropropylene‐ Vinylidene Fluoride Terpolymer (THV)

Polymer Engineering &Science, EarlyView.
Strain‐optical time slice study and evolution of microstructure via wide and small angle X‐ray scattering patterns and AFM images for uniaxially oriented THV and ETFE films at 145°C. ABSTRACT This study investigates morphological changes during the uniaxial orientation of two fluorinated polymers, ETFE and THV.
