Numerical and experimental study of thermally induced wavefront aberration in a direct-liquid-cooled Nd:YLF thin-disk laser gain module

The wavefront aberration induced by thermally in a direct-liquid-cooled Nd:YLF thin-disk laser gain module is investigated numerically with the laminar flow pattern. We find that the liquid layer plays the major role in causing of the wavefront aberration in the gain module. The...

Cross-Frequency Dependence Overlap in the Chinese A-Share Dependence Network

Multiresolution analysis is widely applied to equity markets on the assumption that different frequency bands capture distinct trading behaviors and information flows. Whether those bands reveal structurally distinct equity communities, or mostly re-express a shared dependence ba...

Strongly coupled stimulated Brillouin amplification with flying focus

Damage to compression gratings poses a fundamental limit to chirped pulse amplification in high-power laser systems. Plasma-based compressors using strongly coupled stimulated Brillouin scattering (scSBS) offer a damage-free alternative, but their effectiveness has been hindered...

A Modified Delphi Study on the Ethics and Governance of Live Injecting at Aesthetic Conferences. Is There a Better and Safer Alternative?

BACKGROUND: Live clinical demonstrations at aesthetic medicine conferences is common, yet concerns regarding patient safety, commercial influence, and ethical governance. This study established a consensus-based governance framework for live injecting and compared expert and atte...

Healing intervention for improving the efficiency and stability of tandem devices on industrial textured silicon

Monolithic perovskite/silicon tandem solar cells are widely regarded as the next-generation, low-cost, high-efficiency photovoltaic technology. However, achieving high-quality wide-bandgap perovskite top cells on industrial textured silicon, particularly using hybrid two-step dep...
