We report on the welding of various glasses with ultrashort laser pulses. Femtosecond laser
pulses at repetition rates in the MHz range are focused at the interface between two …

In binary aluminosilicate liquids and glasses, heterogeneity on intermediate length scale is a
crucial factor for optical fiber performance, determining the lower limit of optical attenuation …

Raman scattering is performed in three sets of aluminosilicate glasses with light cations and
concentrations varying from peralcaline to peraluminate domain. The depolarized spectra …

Microscopic deformation processes determine defect formation on glass surfaces and, thus,
the material's resistance to mechanical failure. While the macroscopic strength of most …

The temperature and chemical dependence of the melt viscosity are ubiquitous in the model
development of the volcanic dynamics, as well as in the glass production and design. We …

The liquid viscosity of multiphase systems is usually retrieved by the use of combined
chemical analysis and empirical chemistry-based models. Here we present an alternative …

During earthquake propagation, geologic faults lose their strength, then strengthen as slip
slows and stops. Many slip-weakening mechanisms are active in the upper-mid crust, but …

Collective modes and dynamics of dense disordered materials such as water are not well
understood, but nonlinear optics provides a sensitive probe to study polar modes in these …

This paper focuses on the densification signature measured by Raman spectroscopy in
silica-based glasses. We have studied a pure silica glass and a 25GeO 2–75SiO 2 binary …

The aim of this paper is to provide an overview of advances in the field of Raman
spectroscopy as reflected in articles published each year in the Journal of Raman …
