Acoustic damping and dispersion in vitreous germanium oxide
Guillaume Guimbretière, Benoît Rufflé, René Vacher
New Brillouin scattering measurements of velocity and attenuation of sound in the hypersonic regime are presented. The data are analyzed together with the literature results at son…
Eliminating the broadening by finite aperture in Brillouin spectroscopy
R. Vialla, B. Rufflé, G. Guimbretière +1
We present a new optical arrangement which allows to avoid the broadening by finite aperture in Brillouin spectroscopy. In this system, all the rays scattered at the same angle by…
Acoustic damping in LiO-2BO glass observed by inelastic x-ray and optical Brillouin scattering
B. Rufflé, G. Guimbretière, E. Courtens +2
The dynamic structure factor of lithium-diborate glass has been measured at several values of the momentum transfer using high resolution inelastic x-ray scattering. Much atten…
Glass-specific behavior in the damping of acoustic-like vibrations
B. Rufflé, G. Guimbretière, E. Courtens +2
High frequency sound is observed in lithium diborate glass, LiO--2BO, using Brillouin scattering of light and x-rays. The sound attenuation exhibits a non-trivial depen…
