“…In fact, if the strengthening of frozen fluctuations is due to internal stresses, then it should depend on the cooling and annealing regime. Results from a study of the influence of technical synthesis regimes, the purity of the starting components, and the preparation methods on the optical and refraction parameters of chalcogenide glasses confirmed this [19]. Apparently the fact that a large nonequilibrium in the structure arises upon cooling the melt at fast rates and leads to an increase of not only the structural but also the chemical disorder should also be considered [6].…”

535.36:548Raleigh and Mandelshtam-Brillouin light scattering has been investigated in chalcogenide glasses of the (As 2 S 3 ) x I 1-x system for x = 1.00-0.80. Longitudinal hypersound velocities, adiabatic elastooptical constants (p 12 ) ad at frequencies of ~15 GHz, and Landau-Placzek ratios R LP are found and scattering losses are calculated. Significant iodine additives are shown to result in the appearance of different features in the behavior of concentration dependences of the investigated parameters.
