Residual processing defects significantly reduce fused silica optics' laser-induced damage threshold (LIDT), which seriously limits their performance and lifetime in high-energy laser applications.

a, conventional process chain. b, CO2 laser process chain. c, 3D-space full aperture characterization method of SSD. Residual processing defects significantly reduce fused silica optics' laser-induced ...

Laser-induced damage in fused silica optics represents a critical challenge for modern high-power laser systems. This phenomenon is predominantly initiated by microscopic defects—such as scratches, ...
