To date, it is controversial which metallic impurities play crucial role in the laser induced
degradation and damage of fused silica at 355 nm. In this work, a First-principles study for …

摘要熔石英光学元件在高能量密度的紫外脉冲激光辐照下往往极易出现后表面损伤,
这严重影响了紫外高功率脉冲激光装置的可靠性. 综合国内外相关研究进展 …

Many kinds of subsurface defects are always present together in the subsurface of fused
silica optics. It is imperfect that only one kind of defects is isolated to investigate its impact on …

Inert ion beams with large incident angle were used for layer by layer etching of chemical-
mechanical polished fused silica. The evolution of the impurities, subsurface defects, surface …

Detection and measurement of subsurface damage of ground optical surfaces are of major
concern in the assessment of high damage thresholds fused silica optics for high power …

We report an experimental investigation of fluorescence confocal microscopy as a tool to
measure subsurface damage on grinded fused silica optics. Confocal fluorescence …

The material response following nanosecond, UV laser induced breakdown inside of the exit
surface of fused silica is investigated using multimodal time resolved microscopy. The study …

Subsurface defects of fused silica optics would vary with HF-etched process. In this paper,
the subsurface defects characteristics of HF-etched fused silica optics and their effects on …

Since fused silica material possesses good mechanical properties, thermal and optical
properties, such as high hardness, low coefficient of thermal expansion, and wide …

We investigate the capacity of magnetorheological finishing (MRF) process to remove
surface and subsurface defects of fused silica optics. Polished samples with engineered …
