LIBS-Based Classification of Thermal Aging Levels in High-Voltage Wire Harnesses of New Energy Vehicles Using MAD-RF

High-voltage wiring harnesses in new energy vehicles (NEVs) are susceptible to thermal aging in high-temperature environments, whereas conventional assessment methods are difficult to deploy rapidly. This study combines laser-induced breakdown spectroscopy (LIBS) with random fore...

CO2 laser processing of fused silica: a review of mechanisms, defect control and functionalization

Fused silica optics are critical components in inertial confinement fusion facilities, where they are exposed to intense ultraviolet laser radiation. However, processing induced subsurface defects serve as laser damage precursors, severely degrading the laser-induced damage thres...

Simultaneous Ce Ion Doping in Core and Cladding to Enhance the Radiation Resistance of Erbium-Doped Fibers

Erbium-doped fibers (EDFs) suffer from radiation-induced absorption (RIA) and radiation-induced gain variation (RIGV) under ionizing radiation, which limit their applications in space optical communication systems. To address this issue, a novel core–cladding Ce co-doped fiber is...
