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 ...

Misalignment‐Robust Dynamic Cascaded Holography Accelerated by Deep Neural Networks

Laser &Photonics Reviews, EarlyView.
Cascaded holography has mainly been studied using metasurfaces. Here, we demonstrate a fully dynamic cascaded holographic system based on two phase‐only spatial light modulators. A misalignment‐tolerant optimization method preserves image quality despite alignment errors, making cascaded holographic systems simpler, more reliable, and easier to use in ...

Investigation of the Effects of Surface and Heat Treatment on the Corrosion Behavior of Additively Manufactured AlSi10Mg

Materials and Corrosion, EarlyView.
Surface finish and heat treatment strongly affect the corrosion behavior of AM AlSi10Mg. Polished samples show the highest corrosion resistance, while as‐built ones suffer from surface roughness and weak oxide layers. Stress relief (SR300) improves the corrosion potential but lowers pitting resistance due to Si network dissolution.

Exploring patterns for social‐ecological success of ecosystem restoration worldwide

People and Nature, EarlyView.
Abstract Ecosystem restoration is a crucial response to human‐induced land degradation, which threatens biodiversity and ecosystem functions, poses food and water insecurity and undermines livelihoods, cultural values and human–nature relationships. For restoration to be effective and equitable, it is essential to understand how social and ecological ...
