How small stresses affect 351-nm damage onset in fused silica

This paper presents an innovative technique for designing high-strength optical glasses in which slow crack growth is arrested and the laser-induced damage threshold is significantly higher. The technique consists simply of applying compressive stresses in the surfaces of a glass. An increase of up to 70 percent in fused-silica exit-surface as well as front-surface threshold has been obtained.
