Abstract

The study of light scattering by the barium sodium niobate crystals has been performed in range of 20-800°C at the excitation of the crystal by argon (514,5 nm) and helium neon (λ=630.0nm) lasers. At heating from room temperature near 500°C the laser observed increasing far field spot dimension for λ=514.5 nm. It was observed also on heating, that the elastic light scattering intensity increases near the ferroelectric phase transition (T_c=550°C) for λ=632.8 nm in contrast with decrease for λ=514.5 nm. It have related our measurements to results of x-ray and electron microscope investigations by works.^3,4
