POSTER SESSION B Irradiation defects in superhard cubic boron nitride single crystals

Abstract

The damage threshold of fused silica in vacuum and air before or after 355nm laser irradiation is measured. The structure and defects of fused silica has been studied by means of FTIR (Fourier transform infrared), Raman and Fluorescence spectroscopy. The primary defect species are oxygen vacancies (such as Si–Si bonds), non-bridging oxygen hole center… (More)
