HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Structural relaxation and quasi-elastic light scattering in glass: Approach by ferroelectric and ion-conducting phases

“…In terms of amorphous solids, it has been proposed that the QLS phenomenon is closely related to the fast β-relaxation process 17 18 19 . Because 3D-interlinked NbO 6 units or the NbO 6 -nanodomain region has been verified in high-Nb 2 O 5 -content glasses 8 20 21 , the QLS studies of ferroelectrics would shed light on the QLS in glass. In other words, these studies help us to clarify the QLS in glass based on the analogy of the medium-range structure.…”

Thermal Poling of Optical Glasses: Mechanisms and Second‐Order Optical Properties

“…This general scaling is proposed on the base of several study from some of us or taken in the literature. [54][55][56][57][58] Thus, following the criterion of the highest v (3) , the most interesting glasses are chalcogenide glasses and tellurite glasses that are, respectively, two and one order of magnitude greater than SiO 2 . Oxide glasses that contain d°ions are also good candidate, but their third-order optical response will mainly depend on the ability of the glass matrix to sustain high loading of Ti 4+ , Nb 5+ , or W 6+ cations.…”

“…, the third‐order nonlinear optical properties of the main glass families have been scaled in reference to SiO 2 . This general scaling is proposed on the base of several study from some of us or taken in the literature . Thus, following the criterion of the highest χ (3) , the most interesting glasses are chalcogenide glasses and tellurite glasses that are, respectively, two and one order of magnitude greater than SiO 2 .…”

Springer Handbook of Glass

“…Based upon the Born-Oppenheimer approximation, several measurements of the nuclear contribution in glasses have been performed in the femtosecond regime using timeresolved techniques to separate out the electronic and the vibrational contributions [8]. [29][30]…”
