Abstract :
The results of Brillouin light scattering measurements in bulk halide glasses are described. The Brillouin linewidth, intensities and frequency shift measurements allowed the calculation of phonon attenuation, Pockels´ elasto-optic coefficients and stimulated Brillouin scattering gain coefficients. The above study shows that the threshold power for stimulated Brillouin scattering in some halide glasses is greater than that for silicate glasses.
