Glass for photonics: insight in the glass properties obtained under laser fs writing via point defects analysis (Invited Paper)
8 April 2024 • 16:30 - 17:00 CEST | Amsterdam/Salon 6, Niveau/Level 0
Abstract
Multi-scale 3D architecture with highly localized fluorescence contrast in photosensitive silver-containing glasses by means of femtosecond laser writing can be obtained. We will present results obtained on electron-irradiated glass samples by EPR spectroscopy and in-situ cathodoluminescence. This allowed for understanding the initial phenomena of electron deposition and charge trapping by identifying the nature of point defects and Ag species. In addition, a careful point defects analysis of fs-laser written silica glass as a function of the laser deposited energy for [50-500 fs] pulse durations was leaded highlighted the role of certain defects in the chemical etching of fused silica glass

Dr. Nadège Ollier is a senior Researcher at Atomic Energy and Alternative Energies Commission (Laboratoire des solides Irradiés, IP Paris France). She earned her doctoral degree in 2002 and defended her habilitation in 2012. She serves on the International Advisory Board of PNCS and is a TC Chair for ICG. Nadège was co-chairman of REI-19 conference in 2017.
Nadège Ollier’s research and activities deal with irradiation effects in oxide glasses. She is specialist of the glass point defects and structural evolution under irradiation. She was in particular interested in the degradation of the glass optical properties under ionizing irradiation in Optical fibers (i.e photodarkening of Yb doped fibers). Her current research interest focuses on dosimetry and densification mechanisms of silica glass as well as archeometry. She authored one book chapter and more than 70 papers.
