136.9 W Acousto‐Optically Q‐Switched 2 μm Thin‐Disk Laser

Advanced Photonics Research
We demonstrate an acousto‐optic (AO) Q‐switching Ho:YAG thin disk laser (TDL) at 2 μm with Tm‐fiber laser pumping. Under continuous‐wave operation, the laser delivered a maximum output power of 216.4 W with an optical‐to‐optical efficiency of 43.28 ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Tungsten Molecular Species in Deuterium Plasmas in Contact with Sputtered W Surfaces

Molecules
We show that in plasmas generated in deuterium in the presence of sputtered W surfaces, various molecular tungsten species are formed, whose chemical composition depends on the presence of gaseous impurities, namely, nitrogen, oxygen, and hydrogen.

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Enantio-selective vibronic coupling revealed via dissymmetry of upconverted emission in double-resonance excitation of chiral polymer

Nature Communications
Double-resonance dual-beam spectroscopy, involving vibrational and electronic transitions, is a powerful tool allowing to resolve vibronic coupling in complex molecular systems. Here, introducing resonant three-photon excitation with mid-infrared beam in
